Q. Consider the following statements regarding homologous series:

1. The melting point increases as we go down in a series.
2. It is a series with different functional groups.

Select the correct answer from the codes given below:
Answer: Only 1
Notes: A homologous series comprises compounds with the same functional group and similar chemical properties, but with increasing molecular mass, leading to a gradual increase in physical properties like melting point. All members share the same functional group; hence, statement 2 is incorrect. Statement 1 is correct as melting point generally increases down the series.
