Hybridization

Its hybridization is sp³ and the shape is angular

Please explain it...

In NH₂^-, there are two bond pairs and two lone pairs.
From bp+lp rule, bp+lp=4
so the hybridization is sp³.
As the hybridization is sp³, the shape should be tetrahedral. But due to presence of lone pairs it is distorted and it becomes angular.
Also the angle between the bond reduces. This is because the repulsion between the lone pairs is more than that of bond pairs.

we can also use hybr formula..

total no. of valence electrons in NH2- =5+2+1(-VE CHARGE)=8

8/2=4

1st quotient=4
remainder =0

so hybridisation=sp3

and since lonepairs are there, so shape becomes angular...
