Which of the following has\[s{{p}^{2}}-\]hybridisation?

A)  \[{{C}_{2}}{{H}_{6}}\]           

B)  \[{{C}_{2}}{{H}_{4}}\]

C)  \[BeC{{l}_{2}}\]           

D)  \[{{C}_{2}}{{H}_{2}}\]

Correct Answer: B

Solution :

[b] When there is\[3\sigma \]bonds, the hybridisation is \[s{{p}^{2}}\]. The structures of the given compounds are [a] [b] [c] [d] Thus,\[C{{H}_{2}}=C{{H}_{2}}\]has\[s{{p}^{2}}\]hybridisation.
