tips and tricks OF THE DAY

  • Ex: A compound X with seven carbon atoms on treatment with Br2 and KOH gives Y. Y gives carbylamine test and upon diazotisation and coupling with phenol gives azodye. X is
    (A) C6H5CONH2
    (B) CH­3 – (CH2)5 – CONH2
    (C) CH3 –C(CH3)2 - CH­2 – CH2 – CONH2
    (D) O – CH3 – C6H4NH2
    Explanation: Since Y gives coupling reaction after diazotisation it suggest that Y can be aniline or benzener ring substituted aniline. Since Y has been obtained from Hoffmann bromamide it means has – CO NH2 group with benzene ring. Hence it is C6H5CONH2
