Q40 / 160 · TS EAMCET 2018 (04 May Shift 1) · Chemistry

Which product of the following reactions fails to give the carbylamine test ?

A
Hoffmann bromide degradation
B
Gabriel phthalimide synthesis
C
Reduction of nitrites with ${LiAlH}_{4}$
Correct answer
D
Reduction of tertiary amides with ${LiAlH}_{4}$

Solution

The secondary and tertiary amines do not exhibit carbylamine reactions. As tertiary amides are derived from secondary amines, reduction of tertiary amides with

{LiAlH}_{4}

fails to give the carbylamine test.

Hence, the correct answer is option: 'D'.
