Bond length between hybridised carbon atom and other carbon atom is minimum in

Options

(a) propene
(b) butane
(c) propane
(d) propyne

Correct Answer:

propyne

Explanation:

The C – C bond length = 1.54Å,

C = C bond length = 1.34 Å and C ≡ C bond length = 1.20Å.

Since propyne has a triple bond, therefore it has minimum bond length.
