Question

Assertion `:` is `3-`methyl cyclopentene.
Reason `:` In numbering, double bonded carbon atoms gets preference to the alkyl group in cycloalkenes.
A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both the assertion and reason are true but the reason is not the correct explanation of assertion.
C. If the assertion is true but reason is false.
D. If assertion is false but reason is true.

Answer 1

Correct Answer - a
In naming cycloalkenes, number the ring to give the double bonded carbons 1 and 2 and choose the direction of numbering so that the substituents get the lowest numbers. The position of the double bond is not indicated because it is known to bond between `C-1` and `C-2`.
