Question

Which of the following species are involved in the carbylamines test?

(i) RNC (ii) $\mathrm { CHCl } _ { 3 }$

(iii) $\mathrm { COCl } _ { 2 }$ (iv) $\mathrm { NaNO } _ { 2 } + \mathrm { HCl }$

• A. (i) and (iv)
• B. (i) and (ii)
• C. (ii) and (iv)
• D. (ii) and (iii)

Answer 1

Answer: (B)

(i) and (ii)

Answer 2

:

$\mathrm { RNH } _ { 2 } + \mathrm { CHCl } _ { 3 } + 3 \mathrm { KOH } \xrightarrow { \Delta } \mathrm { RNC } + 3 \mathrm { KCl } + 3 \mathrm { H } _ { 2 } \mathrm { O }$ only RNC and $\mathrm { CHCl } _ { 3 }$ are involved in carbylamine reaction.
