Vedclass · Answer

(D) $CH_3MgX$ is a Grignard reagent,which acts as a strong base. Terminal alkynes like $CH_3-C \equiv CH$ contain an acidic hydrogen atom attached to the $sp$-hybridized carbon. The Grignard reagent abstracts this acidic proton to form an alkane. The reaction is: $CH_3MgX + CH_3-C \equiv CH \rightarrow CH_4 + CH_3-C \equiv C-MgX$. Therefore,the product formed is methane $(CH_4)$.
