Answer: There are 4 monofluoro derivatives of methylcyclopentane. Only 1 derivative has flourine atom attached to a primary carbon.
Explanation: The compound methylcyclopentane has 1-primary carbon, 4- secondary carbons and 1-tertiary carbon.
1) Primary carbon (1°): In this the carbon atom is attached directly to only one carbon atom.
2) Secondary carbon (2°): In this the carbon is attached directly to two carbon atoms.
3) Tertiary Carbon (3°): In this the carbon is attached directly to three carbon atoms.
The monofluoro derivatives are shown in the image below.
Structure B is the only derivative which has fluorine attached to primary carbon atom.
