C

Text Solution

Verified by Experts

The correct Answer is:
A
The structure :
`CH_(3)-CH_(2) - CH_(2) - overset(CH_(3))overset(|)underset(CH_(3))underset(|)C- underset(C_(2)H_(5))underset(|)(CH) - CH_(2) -CH_(3)`
While writing IUPAC name, alkyl groups are written in alphabetical priority, thus lower locant 3 is assigned to ethyl.
