Identify the molecules which have s p -hybridised carbon(s) from the lisst given under. I. Ethane nitrile, II. Buta-1, 3-diene, III. Propan-1,2-diene, IV. Ethyne V. Benzene

Step-by-step solution

( ) s p -hybridised carbon must have two -bonds. The following molecules have atleast one carbon that possess 2 -bonds. However, given below none of the carbon atom in the molecules have 2 -bonds, so none of them is s p -hybridised.
