Which of the following product is formed in the reaction \[C{{H}_{3}}MgBr\xrightarrow[(ii)\,{{H}_{2}}O]{(i)\,C{{O}_{2}}}?\]

A)  Acetic acid  

B)  Methanoic acid

C)  Methanol   

D)  Ethanal

Correct Answer: A

Solution :

 \[C{{H}_{3}}MgBr\xrightarrow[{}]{C{{O}_{2}}}C{{H}_{3}}COOMgBr\] \[C{{H}_{3}}COOMgBr\xrightarrow[{}]{{{H}^{+}}O{{H}^{-}}}\underset{Acetic\text{ }Acid}{\mathop{C{{H}_{3}}COOH}}\,\]
