1.	Assertion (A) : Among isomeric pentanes, 2,2-dimethyl-pentane has highest boiling point. Reason (R) : Branching does not affect the boiling point.
Answer» Both A and R are correct and R is the correct explanation of A. Both A and R are correct and R is not the correct explanation of A. Both A and R are not correct. A is not correct but R is correct. Solution :Among ISOMERIC pentanes 2,2-dimethyl PENTANE has lowest boiling POINT and on branching boiling point DECREASES.
