Question

What is the shape
of N3-?​

Answer 1

Answer:

linear

Explanation:

Answer 2

$N_{3} ^{-}$  has a linear structure.

• The chemical formula  $N_{3} ^{-}$  represents an Azide ion. The Azide ion is the conjugate base of  the Hydrazoic acid (HN3). It is composed of the 3 Nitrogen atoms & can have the multiple resonance structures.

• The central of Azide ion is N, forms the double bond with other 2 N atoms. Thus it has the 2 bonding domains & no lone pair of the electrons. This gives that it the hybridization of sp.

• The Azide ion  ( $N_{3} ^{-}$ )  has the 3 N atoms. In the lewis structure of  $N_{3} ^{-}$  ion contains 2 N = N bonds. Each of the outside N atoms have 2 lone pairs & the center nitrogen atom doesn't have lone pairs. There are charges on all the nitrogen atoms.

Hence the Shape  $N_{3} ^{-}$ is Linear.
