MCQ
Consider the species $N{O_3}^-,NO_2^ + $ and $NO_2^ - $. Pick up the correct statement:
  • A
    The hybridisation state of $N$ in all the phase is same
  • B
    The shape of $NO_2^ - $ is bent while $NO_3^ - $ is pyramidal
  • ✓
    The hybrid state of $N$ in $NO_3^ - $ and $NO_2^ - $ is same
  • D
    The hybrid state of $N$ in $NO_2^+$ is $sp^3$
✓

Answer

Correct option: C.
The hybrid state of $N$ in $NO_3^ - $ and $NO_2^ - $ is same
c
From the above figure, the hybridization of chemical species are-

$NO _3{ }^{-}- sp ^2$ hybridized with three bond pairs.

$NO _2^{+}-s p$ hybridised with $2$ bond pairs.

$NO _2{ }^{-}- sp ^2$ hybridized with $2$ bond pairs and one lone pair.
