Question

The hybridization states of the nitrogen atom in pyridine piperidine and pyrrole are respectively
A. `sp^(2),sp^(3)andsp^(2)`
B. `sp^(2),sp^(2)andsp^(2)`
C. `sp^(3),sp^(3)andsp^(3)`
D. `sp^(2),sp^(3)andsp^(3)`

Answer 1

Correct Answer - A
In pyridine the steric number of `N` is three as it bonded to two C atoms and carries one lone pair thus `sp^(2)` hybridized In piperdine the steric number of `N` is four as it is boned to two C atoms one `H` atom and carries one lone pair thus `sp^(3)` hybridized In pyrrole the steric number of N atom is three as its lone pair of electrons is involved in resonane with the benzene ring thus `sp^(2)` hybridised
