Question
Which one of the following species has plane triangular shape?
A.
$${N_3}$$
B.
$$NO_3^ - $$
C.
$$NO_2^ - $$
D.
$$C{O_2}$$
Answer :
$$NO_3^ - $$
Solution :
Species with $$s{p^2}$$ hybridisation are planar triangular in shape. Among the given species $$NO_3^ - $$ is $$s{p^2}$$ hybridised with no lone pair of electrons on central atom, $$N$$ . Whereas, $${N_3},NO_2^ - $$ and $$C{O_2}$$ are $$sp$$ hybridised with a linear shape.
