Question

Which amine amongst the following will answer positively the carbylamines test (i.e. heating with $\mathrm { CHCl } _ { 3 }$ and KOH)?

• A. $\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } - \mathrm { NH } - \mathrm { CH } _ { 3 }$
• B.
• C. $\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } - \mathrm { NH } - \mathrm { C } _ { 4 } \mathrm { H } _ { 9 }$
• D. $\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } - \mathrm { N } \left( \mathrm { C } _ { 2 } \mathrm { H } _ { 5 } \right) _ { 2 }$

Answer 1

Answer: (B)

Answer 2

: Only amines (i.e. in the present case) give positive carbylamine reaction.
