Which of the following reactions show nucleophillic substitution of alkyl halide?

A$$R-X+H_{2}\rightarrow RH+HX$$
B$$R-X+KCN\rightarrow RCN+KX$$
Correct Answer
C$$2R-X+2Na\rightarrow R-R+2NaX$$
D$$R-X+Mg\rightarrow RMgX$$

Solution

Among all given reactions, $$X^-$$ nucleophile is replaced by other nucleophile in this reaction only.
$$R-X+KCN\rightarrow RCN+KX$$, here $$X^-$$ is replaced by $$CN^-$$.
