Vedclass · Answer

(A) Alcohols $(R-OH)$ contain an acidic hydrogen atom attached to an oxygen atom. When an alcohol reacts with a Grignard reagent $(R'-MgX)$,the Grignard reagent acts as a strong base and abstracts the acidic proton from the alcohol. The general reaction is: $R-OH + R'-MgX \rightarrow R'-H + Mg(OR)X$ Here,$R'-H$ is an alkane. For example,as shown in the image: $CH_3OH + C_2H_5MgBr \rightarrow C_2H_6 + Mg(OCH_3)Br$ Thus,the product formed is an alkane. Therefore,the correct option is $(A)$.
