When \[C{{H}_{3}}COOH\] reacts with \[C{{H}_{3}}-MgX\]

A) \[C{{H}_{3}}COX\] is formed

B) hydrocarbon is formed

C)  acetone is formed

D)  alcohol is formed

Correct Answer: B

Solution :

Key Idea Grignard reagent on reaction with any compound containing active H-atom decompose to give alkene. (When H-atom is attached to O, N or S or acidic in nature then it is known as active H-atom) In \[C{{H}_{3}}COOH\] active H-atom is present. So, when it reacts with \[C{{H}_{3}}Mg\,X\], then a hydrocarbon is formed. \[C{{H}_{3}}COOH+C{{H}_{3}}MgX\to C{{H}_{4}}+\]\[C{{H}_{3}}COOMgX\] Note - R - Mg - X
