Draw the structures of all monofluoro derivatives of methylcyclopentane, c6h11f, which have the fluorine on a primary carbon.
STatiana [176]

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.
