Question

The H-S-H bond angle in $H_{2}S$ is 92.2° whereas the H-O-H bond angle in $H_{2}O$ is 104.5°, why?

Answer 1

This is due to dipole dipole interaction..

O is highly electro negative whereas S is not soo electro negative...

There happens the repulsive action and so the angle in H2O is more...

Hope it helps you..
