Sample questions

1. 1.Arrange in INCREASING order of basic strength: C2H5NH2, C6H5NH2, NH3, C6H5CH2NH2 and (C2H5)2NH.
   • A.C6H5NH2 < NH3 < C6H5CH2NH2 < C2H5NH2 < (C2H5)2NH
   • B.(C2H5)2NH < C2H5NH2 < C6H5CH2NH2 < NH3 < C6H5NH2
   • C.NH3 < C6H5NH2 < C6H5CH2NH2 < C2H5NH2 < (C2H5)2NH
   • D.C6H5CH2NH2 < C6H5NH2 < NH3 < C2H5NH2 < (C2H5)2NH
2. 2.The conversion of a primary aromatic amine into a diazonium salt is called:
   • A.Diazotisation
   • B.Acylation
   • C.Ammonolysis
   • D.Coupling
3. 3.Assertion (A): The amine formed by the Hoffmann bromamide degradation of an amide contains one carbon atom less than the amide. Reason (R): In the Hoffmann bromamide reaction an alkyl or aryl group migrates from the carbonyl carbon of the amide to the nitrogen atom.
   • A.Both A and R are true and R is the correct explanation of A
   • B.Both A and R are true but R is NOT the correct explanation of A
   • C.A is true but R is false
   • D.A is false but R is true
4. 4.Assertion (A): In trimethylamine the C-N-C bond angle is less than 109.5 degrees. Reason (R): The unshared pair of electrons on nitrogen exerts a repulsion that compresses the bond angle below the regular tetrahedral value.
   • A.Both A and R are true and R is the correct explanation of A
   • B.Both A and R are true but R is NOT the correct explanation of A
   • C.A is true but R is false
   • D.A is false but R is true
5. 5.Aniline reacts with bromine water at room temperature to give as the major product:
   • A.2,4,6-Tribromoaniline (white precipitate)
   • B.p-Bromoaniline only
   • C.o-Bromoaniline only
   • D.Bromobenzene
