The unbranched ( straight chain) alkanes possess

A

`2^(@) and 3^(@)C's`

B

`1^(@) and 2^(@) C's`

C

`1^(@) and 3^(@)C's`

D

`3^(@) and 4^(@)C's`

Text Solution

Verified by Experts

The correct Answer is:
B
In unbranched alkanes, each `C` atom within the chain is bonded to no more than two other `C` atoms and thus, unbranched alkanes contain only primary and secondary `C` atoms.
