(vii) ethanol and ethanamine 
 
10. Explain why : 
 
(i) The C–N–C bond angle in trimethyl amine is 108° 
 
(ii) the quaternary ammonium salts having four different alkyl groups are optically active 
 
(iii) alkylamines are more basic than ammonia 
 
(iv) aniline cannot be prepared by Gabriel phthalimide synthesis 
 
(v) Garbriel phthalimide synthesis is preferably used for synthesising primary amines. 
 
(vi) ethylamine is soluble in water but aniline is not 
 
(vii) amines are soluble in dilute HCl. 
 
(viii) amines have lower boiling point than alcohols of comparable molecular masses. 
 
(ix) 1° amines have higher boiling points than 2° amines which in turn, are higher boiling than 3° amines. 
 
(x) The pKb value of benzeneamine is 9.33 while that of ammonia is 4.75. 
 
(xi) aniline does not undergo Friedel-Crafts reaction. 
 
(xii) aniline readily forms 2, 4, 6-tribromoaniline on reaction with bromine water. 
 
(xiii) sulphanilic acid is soluble in water. 
 
(xiv) methylamine in water reacts with ferric chloride to precipitate hydrated ferric oxide. 
 
(xv) diazonium salt of aromatic amines are more stable than the diazonium salts of aliphatic amines. 
 
(xvi) Although amino group is o, p-directing in aromatic electrophilic substitution reactions, aniline on nitration gives a substantial amount of m-nitroaniline. 
 
11. Why do amines act as nucleophiles? Give example of a reaction in which methylamine acts as a nucleophile. 
 
12. Three isomeric amines A, B and C have the molecular formula C3H9N.Compound A on reaction with benzene sulphonyl chloride forms a product which is soluble in NaOH. Compound B on reaction with benzene sulphonyl chloride forms a product which is insoluble in NaOH and compound C does not react with benzene sulphonyl chloride. Identify A, B and C. 
[Ans. : (A) CH3CH2CH2NH2 (B) CH3CH2NHCH3 (C) (CH3)3N] 
 
13. An organic compound A (C2H3N) is used as a solvent of choice for many organic reactions because it is not reactive in mild acidic and basic conditions. Compound A on treatment with Ni/H2 forms B. When B is treated with nitrous acid at 273K, ethanol is obtained. When B is warmed with chloroform and NaOH, a foul smelling compound C formed. Identify A, B and C. 
[Ans. : (A) CH3CN (B) CH3CH2NH2 (C) CH3CH2NC 
 
14. An organic compound [A] C3H6O2 on reaction with ammonia followed by heating yield B. Compound B on reaction with Br2 and alc. NaOH gives compound C (C2H7N). Compound C forms a foul smelling compound D on reaction with chloroform and NaOH. Identify A, B, C, D and the write the equations of reactions involved. 
[Hint : (A) CH3CH2COOH (B) CH2CH2CONH2 
(C) CH3CH2NH2 (D) CH3CH2NC.]
