Question

The systematic naming of the following cycloalkane is :

• A. 6-Methyl bicyclo [3.2.0] heptane
• B. 7-Methyl bicyclo [3.2.0] heptane
• C. 2-Methyl bicyclo [3.2.0] heptane
• D. 3-Methyl bicyclo [3.2.0] heptane

Answer 1

The correct option is A 6-Methyl bicyclo [3.2.0] heptane

Functional group is an alkane, therefore suffix = -ane

The ring structure requires the prefix- bicyclo

Substitute is -methyl at C6

The ring structure is C7 therefore root = Hept

The links contain 3, 2 and 0 carbon atoms = [3.2.0]

Therefore the name of cycloalkane is $6-Methylbicyclo\left[\mathrm{3.2.0}\right]heptane$
