Which of the following molecules, H 2 O or H 2 S, has a higher bond angle, and why?

Options

  1. AH 2 O, because oxygen is more electronegative than sulphur.
  2. BH 2 S, because sulphur has a larger atomic size.
  3. CH 2 O, because of increased bond-pair bond-pair repulsion between oxygen atoms.
  4. DH 2 S, because of stronger hydrogen bonding between sulphur and hydrogen.

Correct answer

A. H 2 O, because oxygen is more electronegative than sulphur.
