Question: The strongest base among the following is...

The strongest base among the following is

A

C6H5NH2\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { NH } _ { 2 }

B

pNH2C6H4NH2\mathrm { p } - \mathrm { NH } _ { 2 } \mathrm { C } _ { 6 } \mathrm { H } _ { 4 } \mathrm { NH } _ { 2 }

C

mNO2C6H4NH2\mathrm { m } - \mathrm { NO } _ { 2 } \mathrm { C } _ { 6 } \mathrm { H } _ { 4 } \mathrm { NH } _ { 2 }

D

C6H5CH2NH2\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { CH } _ { 2 } \mathrm { NH } _ { 2 }

Answer

C6H5CH2NH2\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { CH } _ { 2 } \mathrm { NH } _ { 2 }

Explanation

Solution

: C6H5CH2NH2\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { CH } _ { 2 } \mathrm { NH } _ { 2 } is the strongest base since the lone pair on nitrogen is not involved in any conjugation
