The −OH- \mathrm { OH } group of methyl alcohol cannot be replaced by chlorine by the action of

A

Chlorine

B

Hydrogen chloride

C

Phosphorus trichloride

D

Phosphorus pentachloride

Answer

Chlorine

Explanation

Solution

CH3OH+Cl2→\mathrm { CH } _ { 3 } \mathrm { OH } + \mathrm { Cl } _ { 2 } \rightarrow No reaction

CH3OH+HCl→ZnCl2CH3Cl+H2O\mathrm { CH } _ { 3 } \mathrm { OH } + \mathrm { HCl } \xrightarrow { \mathrm { ZnCl } _ { 2 } } \mathrm { CH } _ { 3 } \mathrm { Cl } + \mathrm { H } _ { 2 } \mathrm { O }

3CH3OH+PCl3→3CH3Cl+H3PO33 \mathrm { CH } _ { 3 } \mathrm { OH } + \mathrm { PCl } _ { 3 } \rightarrow 3 \mathrm { CH } _ { 3 } \mathrm { Cl } + \mathrm { H } _ { 3 } \mathrm { PO } _ { 3 }

CH3OH+PCl5→CH3Cl+POCl3+HCl\mathrm { CH } _ { 3 } \mathrm { OH } + \mathrm { PCl } _ { 5 } \rightarrow \mathrm { CH } _ { 3 } \mathrm { Cl } + \mathrm { POCl } _ { 3 } + \mathrm { HCl }
