Question

The shape of $N{H}_3$ is:

• A. Trigonal pyramidal
• B. Square planar
• C. V-shape
• D. See-saw

Answer 1

The correct option is A Trigonal pyramidal

The nitrogen atom has five valence electron. In $N{H}_3$, three out of five electrons of nitrogen are involved in bonding with three hydrogen atoms whereas the unbounded two electrons make up the single unshared pair of electron. Due to this lone pair, ammonia exhibit trigonal pyramidal shape.
