Which fo the following statements regarding chemical properties of acetophenone are wrong ?
I. It is reduced to methyl phenyl carbinol by sodium acid and ethanol
II. It is oxidised to benzoic acid with acidified `KMnO_(4)`
III. It does not undergo electrophilic substitution like nitration at meta position ltbr. IV. It does not undergo iodoform reaction with iodine and alkali.

Give reasons for the following: (i) tert-buty lbenzene does not give benzonic acid on treatment with acidic KMnO_(4) . (ii)Normally, benzene gives electrophilic substitution reaction rather than electrophilic addition reaction although it has double bond.

In which of the following reactions, water is not formed as one of the products? I. Propanol is oxidised by acidified K_(2)Cr_(2)O_(7) II. Ethanol undergoes complete combustion. III. Methanoic acid reacts with anhyd. Na_(2)CO_(3) . IV. Methanol reacts with sodium metal.

Which of the following statements regarding ethanoic acid and methyl methanoate are correct? (I) They are functional group isomers with molecular formula C_(2)H_(4)O_(2) . (II) They belong to different homologous series (III) They have different chemical properties.

Account for the following: (i) pK_(b) of aniline is more than that of methylamine. (ii) Ethylamine is soluble in water whereas aniline is not. (iii) Methylamine in water reacts with ferric chloride to precipitate hydrated ferric oxide. (iv) Although amino group is o– and p– directing in aromatic electrophilic substitution reactions, aniline on nitration gives a substantial amount of m-nitroaniline. (v) Aniline does not undergo Friedel-Crafts reaction. (vi) Diazonium salts of aromatic amines are more stable than those of aliphatic amines. (vii) Gabriel phthalimide synthesis is preferred for synthesising primary amines.
