Question

If in NH3 formation N uses its pure atomic orbitals then wrong statement is

At least three bond angles are 90

Three sigma bonds with identical strength

Lone pair will be in 2s orbital

Molecule will be in T shape

Open in App

Solution

The wrong statement is
molecule will be in T shape.

Reason:

NH3 has a bond angle of 107 degrees and is pyramidal this is because it has 3 bonded pairs and 1 lone pair. the lone pair repels more than the bonded pairs and this results in the bond angle being 107 degrees.
