Question

Hybridisation of the nitrogen atom, and electron geometry around nitrogen atom in pyridine is :

• A. $s{p}^3$, pyramidal
• B. $s{p}^2$, planar trigonal
• C. $s{p}^2$, linear
• D. $s{p}^3$, tetrahedral

Answer 1

The correct option is B $s{p}^2$, planar trigonal

The lone pair of nitrogen doesn't participate in resonance as it already maintains it's aromaticity hence Nitrogen has two bond pair and one lone pair which means Nitrogen is $s{p}^2$ hybridized and it is planar.

Hence the correct option is B.
