Q. 163.7( 3 Votes )

Which of the following compounds contain all the carbon atoms in the same hybridisation state?
A. H—C ≡ C—C ≡ C—H

B. CH3—C ≡ C—CH3

C. CH2 = C = CH2

D. CH2 = CH—CH = CH2

Answer :

(i) is an alkyne compound having 2 sets of triple bonds. Here each carbon has 2 sigma bonds and 2 pi bonds, therefore each carbon is ‘sp’ hybridized.

(iv) is an alkene with two sets of double bonds. Each carbon has three sigma bonds and one pi bond, each carbon exhibiting ‘sp2’ hybridization.
