Question

Part D Explain which intermolecular force is primarily responsible for the unusually high boiling point of H2 O. Compare the strengths of intermolecular forces of attraction present in a sample of liquid water to the strengths of intermolecular forces of attraction present in liquid samples of H2S, H2Se, and H2 Te. Justify your answer using the information presented in both tables, and complete the statements below Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer.

Explanation / Answer

Hydrogen bonding is the intermolecular force is primarily responsible for the unusually high boiling point of H2O.

There are three types of intermolecular forces present in nature which are, in the ascending order, London dispersion forces or Van der Walls interactions, Hydrogen bonding, Dipole-Dipole Interactions.

In water all of these three intermolecular forces are present while the ability to form hydrogen bond decreases down the group, i.e., H2O>H2S>H2Se>H2Te, other two forces are present.

The strength of the dispersion forces between liquid water molecules is stronger than those of liquid H2S, H2Se, H2Te beacuse water has the highest polarizability.

Liquid water is capable of three types of intermolecular interaction, whereas liquid H2S, H2Se and H2Te are capable of two types of intermolecular interaction and the unusually high boiling point of H2O is primarily due to hydrogen bonding.
