Chemical Bonding and Molecular Structure

Given below are two statements:

Statement I: The boiling points of the following hydrides of group 16 elements increase in the order H2O<H2S<H2Se<H2Te\mathrm{H_2O < H_2S < H_2Se < H_2Te}.

Statement II: The boiling points of these hydrides increase with increase in molar mass.

In the light of the above statements, choose the most appropriate answer from the options given below:

  1. A.Statement I is incorrect but Statement II is correct
  2. B.Both Statement I and Statement II are correct
  3. C.Both Statement I and Statement II are incorrect✓
  4. D.Statement I is correct but Statement II is incorrect

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
