Question

What kind of geometry does $H_{2}S$ have?

Answer 1

It's bent like a water molecule, but with a much sharper bond angle at the sulfur atom than water at its oxygen atom.

Water has a bond angle of about ${104}^0$, but in hydrogen sulfide, the angle is only about ${92}^0$.

This implies that in hydrogen sulfide we have bonding almost entirely with p orbitals. The hybridization we see between the s and p orbitals on the oxygen in water is almost completely absent in $H_{2}S.$
