Answer
A is true but R is not the correct explanation of A.
Reason — Alkenes, alkynes and alkanes are examples of homologous series represented by the same general formula and having a similar structure and similar chemical properties in which the successive compounds differ by a CH2 group. Hence, the assertion (A) is true.
Organic compounds of the homologous series have similar structures and similar chemical properties. Hence, reason (R) is not the correct explanation of assertion (A).
