Question

A molecule $X{Y}_2$ contains two sigma bonds, two pi bonds and one lone pair of electrons in the valence shell of $X$. The shape of molecule is:

• A. linear
• B. angular
• C. tetrahedral
• D. pyramidal

Answer 1

The correct option is B angular

In the given molecule $X{Y}_2$, the central $X$ atom has 2 bond pairs and a lone pair, so the molecule is a $s{p}^2$ hybrid with a lone pair and hence, the shape is angular.
The given description of $X{Y}_2$ is similar to $S{O}_2$.
