Assertion:	A homologous series is a group or class of organic compounds that have the same general formula and similar chemical properties but differ by a \(-CH_2\) group.
Reason:	The successive member in the homologous series has one more methylene group than the preceding member, which is why they are called homologs.

Assertion is wrong, reason is correct
Both assertion and reason are true, but reason is not the correct explanation of assertion
The assertion is correct, but the reasoning is wrong
