In which of the following reactions phenol is not obtained :

A

→NaOH/CaO\xrightarrow { \mathrm { NaOH } / \mathrm { CaO } }

B

→H3O+\xrightarrow { \mathrm { H } _ { 3 } \mathrm { O } ^ { + } }

C

→633 K,300AtmNaOH\xrightarrow [ 633 \mathrm {~K} , 300 \mathrm { Atm } ] { \mathrm { NaOH } }

D

Answer

→H3O+\xrightarrow { \mathrm { H } _ { 3 } \mathrm { O } ^ { + } }

Explanation

Solution

(1)

(2) C6H5 MgBr →H3O+\xrightarrow { \mathrm { H } _ { 3 } \mathrm { O } ^ { + } } C6H6 +

(3)

(4) →ΔH2O\xrightarrow [ \Delta ] { \mathrm { H } _ { 2 } \mathrm { O } }
