पर्याय

• \[\ce{CH3COCH2NHCH3}\]

• \[\ce{CH3CH2COCH2NH2}\]

• \[\ce{CH3CH2CH2CONH2}\]

• \[\ce{CH3CON(CH3)2}\]

Answer 1

A compound 'X' on treatment with Br₂/NaOH, provided C₃H₉N, which gives positive carbylamine test. Compound 'X' is \[\underline{\ce{CH3CH2CH2CONH2}}\].

Explanation:

\[\ce{\underset{(X)}{CH3CH2CH2CONH2} ->[Br2/NaOH][(Hoffmann rearrangement)] \underset{(C3H9N)}{CH3CH2CH2NH2} ->[CHCl3][KOH (Carbylamine reaction)] CH3CH2CH2NC}\]
