Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Wurtz reaction $\Rightarrow$
$R - X + 2 N a + X - R dry ether - ---- \to R - R + 2 N a$
Thus, the given reaction is known as Wurtz reaction and is carried out in presence of dry ether.
Hence, both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
