(a) How do you convert the following:
(i) Phenol to Anisole (ii) Ethanol to Propan-2-ol
(b) Write mechanism of the following reaction:
`C_(2)H_(5)Ohunderset(443 K)overset(H_(2)SO_(4))toCH_(2)=CH_(2)+H_(2)O`
(c) Why phenol undergoes electrophilic substitution more easily than benzene?

Explanation

(a) (i) Phenol to Anisole :

(ii) Ethanol to Propan-2-ol:See Q. 18 (b), Paper 2013, Delhi Board, Set III, (Page 199]
(b) Refer Q. 17 (), Paper-2018 (C), IPage 478].
(c) The rate of any electrophilic substitution reaction depends upon the density in the aromatic ring .Since the electron density is more in phenol than in benzene therefore, phenol undergoes electrophilie substitution more easily than benzene.
