Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Hexane has higher melting points than both pentane and heptane.
Melting point of a straight chain alkane with an odd number of carbons is always less than adjacent homologues with an even number of carbons.
Alkanes with an even number of carbons in the parent chain have better packing efficiency than those containing an odd number of carbons in the parent chain.
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
