1.	An organic compound (A) of molecular formula C_6H_5Cl on reaction with aqueous NaOH gives (B) of formula C_6H_6O. (B) on reaction with NaOH gives (C) of formula C_6H_5ONa. (C) on treatment with C0, followed by acid hydrolysis yield (D) of formula C_7H_6O_3 an aromatic hydroxy acid. Identify A, B, C, D and explain the reactions involved. s
Answer» Solution :(i) (A) is identified from the formula as `C_6H_5Cl`. Chloro benzene. (i) Chloro benzene on TREATMENT with aqueous NAOH yeilds `C_6H_5OH`- phenol as (B). (in) Phenol on reaction with NaOH produces sodium phenoxide, `C_6H_5ONa`as (C ). (iv) Sodium phenoxide on reaction with `CO_2`, FOLLOWED acid HYDROLYSIS, Kolbe.s reaction takesplace to give Salicylic acid as (D).
