Q. Assertion (A) The names of straight chain compounds are based on their chain structure and carry a prefix indicating the number of carbon atoms present in the chain.
Reason (R) From $CH _{4}$ to $C _{4} H _{10}$, the prefixes are derived from common or trivial names.

Organic Chemistry – Some Basic Principles and Techniques

Solution:

The names of straight chain compounds are based on their chain structure and end with suffix '-ane', carry a prefix indicating the number of carbon atoms present in the chain (except from $CH _{4}$ to $C _{4} H _{10}$ where the prefixes are derived from trivial names).
Thus, both $A$ and $R$ are correct and $R$ is not the correct explanation of $A$.
