(a) How will you obtain the following :(i) Benzaldehyde from Phenol (ii) Benzoic acid from Aniline(b) Give reasons :(i) Aldehydes are more reactive than ketones towards nucleophilic reagents.(ii) Electrophilic substitution in benzoic acid takes place at meta position.(iii) Carboxylic acids do not give the characteristic reactions of carbonyl group.
(iii) Rank the carbonyl compounds given below in terms of their relative reactivity with sodium
borohydride.

(iv) Suggest two factors which combine to make the aldehyde react with sodium borohydride at a
different rate from the ketone.
(v) Based on electronegativity one might assume that the ester and acid chloride possess similar
reactivity towards nucleophiles. Suggest why this turns out not to be the case (your answer
should mention resonance and inductive effects).
During a recent synthesis of hispidospermidin, a fungal isolate and an inhibitor of phospholipase C, the investigators employed
employed a novel Friedel-Crafts acylation on a nonaromatic system (J. Am. Chem. Soc. 1998, 120, 4039-4040). The following
acid chloride was treated with a Lewis acid, affording a mixture of two products, 1 and 2. Propose a plausible mechanism for
the formation of compounds 1 and 2.
