o-toluic acid on reaction with \[C{{N}^{-}}\] gives:

A)

B)       

C)  

D)

Correct Answer: C

Solution :

When o-toluic acid is treated with \[(N{{i}^{2+}})\] electrophilic substitution take place. \[(pH=9-11)\] group is o-and -p directing, while \[+3\] is m-directing. Hence, 5-bromo-2-methyl benzoic acid is obtained.
