Question

Systematic nomenclature of ?

• A. $1$-methylbicyclo (4.1.0) heptane
• B. $2$-methylbicyclo (4.1.0) heptane
• C. $4$-methylbicyclo (4.1.0) heptane
• D. $7$-methylbicylo (4.1.0) hetane

Answer 1

The correct option is A $1$-methylbicyclo (4.1.0) heptane

The numbering should start from substituent containing carbon.

$\to$ Two cyclic structure denotes bicyclic

$\to$ In braces ( ) first no. of carbons in larger cyclic structure then second structure and then carbons in the joining line.

$\to$ Lastly a total number of carbon atoms with one. So, we get $1-$ methylbicyclo$(4,1,0)$ heptane
