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
  1. I, II, III only
  2. II, III, IV only
  3. III, IV, V only
  4. I, III, IV only

Solution

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