Question

Maximum bond angle at nitrogen is present in which of the following?
(AIPMT - 2015)

Answer 1

It has 2 $\sigma$ bond pair, so N has $sp$ hybridisation. Hence, its bond angle is ${180}^o$

It has 3 $\sigma$ bond pair, so N has $s{p}^2$ hybridisation. Thus, its bond angle is ${120}^o$

$N{O}_2$ is a bent shape molecule due to the presence of odd electron. Hence, its bond angle is less than ${180}^o$


$N{O}_2^{-}$ is a bent shape molecule due to the presence of lone pair. Hence, its bond angle is less than ${180}^o$


Hence, option (b) is the correct answer.
