Question

In NH3, molecule, there are three........
A)ºsp2-s bonds
C) s-s bonds
C) sp - p bonds
D) ºsp3-s bonds​

Answer 1

the hybridization of ammonia we have to carefully examine the areas around NItrogen. If we look at the atomic number of nitrogen it is 7 and if we consider its ground state it is given as 1s2, 2s2,2p3.

During the formation of ammonia, one 2s orbital and three 2p orbitals of nitrogen combine to form four hybrid orbitals having equivalent energy which is then considered as an sp3 type of hybridization.

Further, if we look at the NH3 molecule, you will notice that the three half-filled sp3 orbitals of nitrogen form bonds to hydrogen’s three atoms. However, the fourth sp3 orbital that is present is a nonbonding pair of hybridized orbital and is normally used for holding the lone pair.

Hence,option 3) is the correct option.

ANSWER :

In NH3 molecule there are three sp³ bonds.
