In which of the following compounds, the bond length between hybridised carbon atom and other carbon atom is minimum?

A

Butane

B

Propyne

C

Propene

D

Butane

Text Solution

Verified by Experts

The correct Answer is:
B
We know `C - C` bond length = `1.54 Å`
That `C = C`bond length `= 1.34Å`
`C -= C` bond length= `1.20 Å`
Since, propyne has triple bond, therefore, it has minimum bond length.
