Molecule in which the distance between two adjacent carbon atom is largest is

A

Ethane

B

Ethene

C

Ethyne

D

Benzene

Text Solution

Verified by Experts

The correct Answer is:
A
Bond length order:
`{:(C-Cgt,C=Cgt,C-=C,,),(154,134,120p m,,):}`
In benzene, due to resonance, the bond length lies in between single and double bond and is `139 p m`.
