How many of the following compounds can respond positive test with CHCl 3 ​ / KOH :

TestHub · Accepted Answer

Explain Question:

The question asks which compounds give a positive test with CHCl₃ + KOH.

Concept:

Only 1° amines give a positive carbylamine test.

Solution:

Only primary (1°) amines give a positive test with CHCl₃ + KOH.

In this reaction, alkyl isocyanide (carbylamine) is obtained as a foul-smelling compound.

$R - N H_{2} + C H C l_{3} + 3 K O H \overset{∆}{\to} R - N C + 3 K C l + 3 H_{2} O$

Among the given options, compounds (I), (II), (IV), (V), (VI), (VII), and (VIII) give a positive test with CHCl₃ + KOH.

Final answer: (7)
