Which of the following compounds has the samallest bond angle in its molecule ?

Options

A. `OH_(2)`
B. `SH_(2)`
C. `NH_(3)`
D. `SO_(2)`

Answer

B

Explanation

In `H_(2)S` due to low electronegativity of Sulphur the L.P. – L.P. repulsion is more than B.P. – B.P. repulsion and hence the bond angle is minimum.
