Difference in Boiling Points for H2O and H2S
Difference in Boiling Points for H2O and H2S
Difference in Boiling Points for H2O and H2S
Higher boiling point of water over hydrogen sulphide is due to: [1]
The correct option is C Hydrogen bonding interactions. As we know, stronger the intermolecular forces, higher will be boiling point
Out of H2O and H2S, which one has a higher bond angle and why? [2]
H2O has a higher bond angle than H2S because as we move from oxygen to sulfur the size of the central atom increases and electronegativity decreases due to which bond moving from the central atom leads to a decrease in bond pair repulsion and therefore the angle is reduced.. Out of H2O and H2S, which one has a higher bond angle and why?

Why does water show a higher boiling point as compared to hydrogen sulphide \[?\] Give reasons for your answer. [6]
Why does water show a higher boiling point as compared to hydrogen sulphide \[?\] Give reasons for your answer.. Hint: The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into gas/vapor.
First, we have to know the boiling points show the strength of forces between molecules. The more they stick together, the more energy it will require to transform liquid state into vapours.
Also, the boiling point of hydrogen sulphide \[ – {60^o}C\].. Water shows higher boiling point as compared to hydrogen sulphide due to the presence of hydrogen bonding between \[O\] and \[H\] in water molecules due to high electronegativity and small size of oxygen atom

Which out of H2O and H2S has higher boiling point and why ?. Water has a higher boiling point than hydrogen sulphide
[Solved] Explain the trend in boiling point below H2O bp 100 C H2S bp 60 C [8]
Explain the trend in boiling point below H2O bp 100 C H2S bp 60 C. Explain the trend in boiling point below? H2O bp = 100 °C H2S bp = − 60 °C H2Se bp = − 41 °C H2Te bp = − 2.2 °C A
Increase in dispersion O to Te & only H2O has hydrogen bonding. The boiling point of H₂O, H₂S, H₂Se, and H₂Te is given as 100°C, – 60°C, – 41°C, and – 2.2°C, respectively.
The boiling point increase with the increase in the intermolecular forces of attraction. The hydrogen bonding and the dispersion forces are the primary force of interaction that is responsible for the increase in the boiling point.
Amongst H2O,H2S,H2SeandH2Tethe one with the highest boiling point is: 1. H2O because of H-bonding. 2. H2Te because of higher molecular weight. 3. H2S because of H-bonding. 4. H2Se because of lower mol [9]

6.5: The Structure and Properties of Water [10]
With 70% of our earth being ocean water and 65% of our bodies being water, it is hard to not be aware of how important it is in our lives. There are 3 different forms of water, or H2O: solid (ice), liquid (water), and gas (steam)
– Surface Tension, Heat of Vaporization, and Vapor Pressure. If you look at the periodic table and locate tellurium (atomic number: 52), you find that the boiling points of hydrides decrease as molecule size decreases
Moving up, the next hydride would be H2Se (hydrogen selenide) with a boiling point of -42°C. One more up and you find that H2S (hydrogen sulfide) has a boiling point at -62°C
Why is the boiling point of H2O higher than boiling point of H2S? [11]
Oxygen, nitrogen, and fluorine have a high boiling point.. The hydrogen bonds between water molecules are stronger.
For example, the boiling point of the ionic compounds copper(II) oxide, CuO, and sodium chloride, NaCl are 2,000 degrees C and 1,413 degrees C, respectively. The boiling point of the molecular compounds carbon tetrachloride, CCl4, and water, H2O are 76.72 degrees C and 100 degrees C, respectively.
Yes, steam is a part of water, when water reaches a boiling point and begins to evaporate, the result is steam.. NaCl (Table Salt) is a solute in H2O, water, the solvent
Which has the highest boiling point H2S or H2Se or H2O? [12]
Water has the highest boiling point, as the hydrogen bonds between the molecules need more energy to break than the hdyrogen bonds in H2S, and H2Se, as Oxygen is much more electronegative than Sulphur of Selenium, so it makes the molecules more polar.. Hydrogen telluride (H2Te) has a higher boiling point than hydrogen sulfide, because the hydrogen telluride molecules have a higher molecular weight, and both the telluride and the sulfide are only weak hydrogen bonders, in contrast to water
Oxygen has a higher electronegativity than sulfur, and therefore forms a more polar molecule, with a greater negative charge on the oxygen and a greater positive charge on the asymmetrically arranged hydrogen atoms. The polarity of the molecule is what causes water molecules to attract other water molecules and this to remain close together in a liquid phase, rather than flying apart into the gas phase
Boiling point of ethanal CH3CHO is 20.2 °C (293.3 K)Boiling point of water H2O is 100 oC (373.1 K). K3P will have the highest boiling point because it’s the only ionic compound in the group
Why at room temperature is H2O a liquid, but H2S is a gas? [13]
This question is basically just asking you why water has a higher boiling point that H2S. So you need to ask yourself what is the factor which means water has a higher boiling point? If you remember back to electronegativies of the elements in the periodic table, you may recall that the elements in the top right hand corner are the most electronegitive (i.e
Furthermore, you may also recall that F, N and O are the three most electronegative atoms in the table. This property means that when they are attached to a hydrogen (which has a much lower electronegativity) there is a difference in electronegativity
Therefore, H2O has a higher boiling point than H2S because H2O has the ability to hydrogen bond whereas H2S does not. Hydrogen bonds are stronger than other intermolecular interactions such as van der Waals interactions or dipole-dipole interations, so require more energy to break them
Why does H2S have a lower boiling point than H2Se? [14]
Originally, I thought h2se would have a lower boiling point since it has more shielding and a larger atomicis radius meaning that the attraction between the nucleus and the outer electrons is weaker and there being easier to break. I also thought that the atomic number ( amount of protons & electrons) was overruled by shielding so it wouldn’t matter if h2se has more electrons than h2s cox it has more shielding and therefore should be lower BP
Which has a higher boiling point h2o or h2s? [15]
The boiling point of water is higher than the boiling point of hydrogen sulphide. Because of the hydrogen bonding in H2O and the small size of the oxygen atom, the intermolecular attractions between water molecules are stronger than those between H2S molecules
When taking all of this into consideration, would it come as a surprise that water has a greater boiling point when compared to h2s because it contains more hydrogen?. Because sulphur does not belong to these elements, the dipole-dipole interaction between 2H2S does not represent a hydrogen bond
Similarly, why is the boiling point of h2s lower than the boiling point of water?. Hydrogen sulphide is less polar than water because sulphur is not nearly as electronegative as oxygen, and as a result, it is not nearly as electronegative as oxygen
SOLVED: Explain why H2S has a lower boiling point than both H2O and H2Se. [16]
