Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ F-CH_2-\overset{O}{\mathop{\overset{||}{\mathop{C}}}}-OH>\underset{\begin{smallmatrix} (Electron-withdrawingcharacter \\ decreasingfromLtoR) \end{smallmatrix}}{\mathop{Cl-CH_2-\overset{O}{\mathop{\overset{||}{\mathop{C}}}}-OH>}} $
$ Br-CH_2-\overset{O}{\mathop{\overset{|}{\mathop{C}}}}-OH $
