Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion Wurtz's coupling reaction of alkyl halide is not suitable for an alkane containing an odd number of carbons in the parent chain.
Wurtz's coupling reaction involves heating of alkyl halides with sodium metal in ether.
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
If an alkane containing an odd number of carbons in the parent chain is to be prepared, two different alkyl halides will have to be used and self -coupling will also take place beside cross coupling.
