Identify the compounds A, B and Cin the following reaction.

$C H_{3} — B r \overset{M g / e t h e r}{\to} [A] \to_{(i i) W a t e r}^{(i) C O_{2}} [B] \to_{∆}^{C H_{3} O H / H^{+}} [C]$

Complete chemical conversion can be done as

\underset{B r o m o m e t h a n e}{C H_{3} - B r} \overset{M g / e t h e r}{\to} \underset{M e t h y l m a g n e s i u m b r o m i d e}{\underset{[A]}{C H_{3} M g B r}} \to_{(i i) W a t e r}^{(i) C O_{2}} \underset{E t h a n o i c a c i d}{\underset{[B]}{C H_{3} C O O H}} \overset{C H_{3} O H / H^{+}}{\to} \underset{M e t h y l e t h a n o a t e}{\underset{[C]}{C H_{3} C O O C H_{3}}}

H e n c e, A = C H_{3} M g B r, B = C H_{3} C O O H,
