Question

The amines are basic in nature hence they form salts with hydrochloric acid. Which of the following will be insoluble in dil. HCl?

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

Answer 1

Answer: (B)

$\left( \mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \right) _ { 3 } \mathrm {~N}$

Answer 2

: There is no free hydrogen in tertiary amines hence they do not form salts and are not soluble in acids.
