The indicator that is obtained by coupling the diazonium salt of sulphanilic acid with N, N-dimethyl aniline is
phenanthroline
methyl orange
methyl red
phenolphthalein
Acetonitrile on reduction gives
propanamine
methanamine
ethanamine
None of these
C.
ethanamine
Cyanides on reduction give 1° amine. Therefore, acetonitrile on reduction gives ethanamine. It can be written as-
