3.2: Carbon [1]
What you’ll learn to do: Discuss why it is said that life is carbon-based and the bonding properties of carbon. You’ve probably heard the term carbon-based life thrown about in scientific conversations before
There are no living things on our planet that do not have carbon (however, there are nonliving things made up of carbon as well: e.g, diamonds and, well, carbon itself).. In this outcome we’ll learn about the importance of carbon to every living thing on earth and its unique properties that make it particularly suited for its role in living things.
Living things are carbon-based because carbon plays such a prominent role in the chemistry of living things. This means that carbon atoms, bonded to other carbon atoms or other elements, form the fundamental components of many, if not most, of the molecules found uniquely in living things

Which Reason Best Explains Why Living Things Need Carbon — I Hate CBT’s [3]
Question: Which pair of molecules both contain carbon atoms?. Question: What is the primary function of the carbon cycle?
Question: Which reason best explains why living things need carbon?. Question: The chemical formula for the major component of palm kernel oil is CH3(CH2)14CO2H
Which statement best describes these macromolecules as foods?. Answer: Palm kernel oil would provide more energy than glucose because it contains more carbon bonds, which release energy when broken.
2.3: Carbon and Organic Molecules [4]
– Identify common elements and structures found in organic molecules. – Explain the importance and use of functional groups
Cells are made of many complex molecules called macromolecules, such as proteins, nucleic acids (RNA and DNA), carbohydrates, and lipids. The macromolecules are a subset of organic molecules (any carbon-containing liquid, solid, or gas) that are especially important for life
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules.. Individual carbon atoms have an incomplete outermost electron shell
5 Molecules and covalent bonding [5]
Covalent bonding is one kind of linking that joins atoms together. The group of atoms held together by covalent bonds is a molecule
Recall what is in molecules of water from Section 2.5.. Which atoms are in a water molecule? How are they bonded together?
You have met three other compounds in the text so far: protein (Figure 10), methane (Question 10) and carbon dioxide (Question 11). These all involve covalent bonding and all exist as molecules
2.3 Biological Molecules – Concepts of Biology – 1st Canadian Edition [6]
– Describe the ways in which carbon is critical to life. – Explain the impact of slight changes in amino acids on organisms
– Understand the functions of the four major types of molecules. The large molecules necessary for life that are built from smaller organic molecules are called biological macromolecules
Combined, these molecules make up the majority of a cell’s mass. Biological macromolecules are organic, meaning that they contain carbon
Molecule Gallery [7]
Alkenes are hydrocarbons which contain carbon-carbon double bonds. Their general formula is CnH2n for molecules with one double bond (and no rings)
Alkenes take part in a wide variety of chemical reactions, and are found as parts of many highly colored systems (see below for examples).. Straight-chain and branched alkenes are named by using the stem that indicates the number of carbon atoms to which is added the suffix -ene
Thus, the word “1-butene” indicates a chain of four carbons, with a double bond between carbons 1 and 2; the word “2-butene” indicates a chain of four carbons, with a double bond between carbons 2 and 3.. Double-bonded carbons are sp2-hybridized, and have trigonal planar shapes, with the bonded atoms at angles of 120° to each other
Explainer: In chemistry, what does it mean to be organic? [8]
Explainer: In chemistry, what does it mean to be organic?. Out of 118 elements, only one has its own field of study: carbon
Carbon-based molecules get special attention because no other element comes close to carbon’s versatility. More types of carbon-based molecules exist than all non-carbon ones put together.
Typically, that element is hydrogen, oxygen, nitrogen or sulfur. Some definitions say that a molecule must contain both carbon and hydrogen to be organic.
Chemical compound – Bonding, Structure, Properties [9]
The carbon atom is unique among elements in its tendency to form extensive networks of covalent bonds not only with other elements but also with itself. Because of its position midway in the second horizontal row of the periodic table, carbon is neither an electropositive nor an electronegative element; it therefore is more likely to share electrons than to gain or lose them
(Other elements, such as phosphorus [P] and cobalt [Co], are able to form five and six covalent bonds, respectively, with other elements, but they lack carbon’s ability to bond indefinitely with itself.) When fully bonded to other atoms, the four bonds of the carbon atom are directed to the corners of a tetrahedron and make angles of about 109.5° with each other (see chemical bonding: Bonds between atoms). The result is that not only can carbon atoms combine with one another indefinitely to give compounds of extremely high molecular weight, but the molecules formed can exist in an infinite variety of three-dimensional structures
It is the enormous potential for variation in chemical properties that has made organic compounds essential to life on Earth.. The structures of organic compounds commonly are represented by simplified structural formulas, which show not only the kinds and numbers of atoms present in the molecule but also the way in which the atoms are linked by the covalent bonds—information that is not given by simple molecular formulas, which specify only the number and type of atoms contained in a molecule
Hydrocarbons [10]
Organic chemistry is the study of the properties of the compounds of carbon. All carbon compounds except for a few inorganic carbon compounds are organic
The simplest Organic compounds are made up of only Carbon and Hydrogen atoms only. Compounds of Carbon and Hydrogen only are called Hydrocarbons.
Each successive member of the series has one more Carbon atom than the preceding member. This series of compounds are called alkanes (CnH2n+2)
Biology for Non-Majors I [11]
– Discuss why it is said that life is carbon-based and the bonding properties of carbon.. Living things are carbon-based because carbon plays such a prominent role in the chemistry of living things
Other elements play important roles in biological molecules, but carbon certainly qualifies as the “foundation” element for molecules in living things. It is the bonding properties of carbon atoms that are responsible for its important role.
Therefore, it can form four covalent bonds with other atoms or molecules. The simplest organic carbon molecule is methane (CH4), in which four hydrogen atoms bind to a carbon atom (Figure 1).
Organic Molecules: Definition & Example [12]
What comes to mind when you hear the word organic? Do you think about produce that is not genetically modified or grown without synthetic chemicals? In biology, you will frequently encounter the terms “organic compounds” or “organic molecules,” but “organic” here takes on an entirely different meaning! So, let’s talk about what organic molecules are.First, we will define organic molecules and…. Explore our app and discover over 50 million learning materials for free.

Chapter 13 – Organic Chemistry [14]
IntroductionOrganic chemistry is the study of carbon based compounds. The structural and genetic materials of living organisms are organic compounds
Because of the manner in which carbon atoms can bond to one another, the number of organic compounds is enormous. In this chapter, we explore some of the fundamental topics of the structure and reactivity of several classes of organic compounds by applying our knowledge of Lewis structures, resonance, and Lewis acid-base theory.
