Chemical Bonding And Molecular Structure Ques 110

110. Which one of the following has the shortest carbon carbon bond length ?

[1992]

(a) Benzene

(b) Ethene

(c) Ethyne

(d) Ethane

Show Answer

Solution:

(c) The bond length decreases in the order $s p^{3}>s p^{2}>s p$.

Because of the triple bond, the carbon-carbon bond distance in ethyne is shortest.
