Question

What will be the geometry and shape of NH2-

Answer 1

ep for NH−2=(V+L+A−C)2=(5+2+1)2 =4

(central atom → N, valence → 5)

4 ep ⇒ Tetrahedral

Now,

ep = 4 & Ligands = 2 ⇒ bp = 2 & lp = 2

Now, the geometry will be tetrahedral but there will be & lone pairs attached to it.

Because of lone pairs, the angle also decreases.

So, it will be having v - shape [Because while deciding shape. Lone pairs are not considered]
