Question 03
The types of hybrid orbitals of nitrogen in NO+2,NO−3 and NH+4 respectively are expected to be
(a) sp,sp3 and sp2
(b) sp,sp2 and sp3
(c) sp2,sp and sp3
(d) sp2,sp3 and sp
Answer: (b) sp,sp2 and sp3
The type of hybrid orbitals of nitrogen can be decided by using VSEPR theory counting bp and as ip in
NO+2=2 bp+0 ip = linear = sp hybridised
NO−3=3 bp+0 ip ⇒=sp2 hybridised
NO+4=4 bp+0 ip ⇒=sp3 hybridised
