Options
Solution
Correct order of acidic strength of major product formed in the given reaction is
(A) 
(B) ${CH}_{3}{CH}_{2} - CHO\underset{\phantom{\Delta\ }}{\overset{\phantom{Ag\left( {NH}_{3} \right)_{2}OH\ }}{\rightarrow}}{CH}_{3} - {CH}_{2} - COOH$
(C) ${CH}_{4} + O_{2}\underset{\phantom{{Na}_{2}{Cr}_{2}O_{7}/H^{+}\ }}{\overset{\phantom{{MO}_{2}O_{3}\ }}{\rightarrow}}HCOOH$
(D) $Ph - {CH}_{2}MgBr + {CO}_{2}\underset{\phantom{H_{3}O^{\oplus}\ }}{\overset{\phantom{\text{~}\text{Dryether}\text{~}\ }}{\rightarrow}}Ph - {CH}_{2} - COOH$
