3. Outline a possible laboratory synthesis of each of the following compounds from alcohols and phenols:
(a) methyl tert - butyl ether
(b) phenetole (C6H5OC₂H5)
(c) n - butyl cyclohexyl ether
(d) p - tolyl benzyl ether
(e) isopropyl isobutyl ether
(f) isopropyl tert - butyl ether
(g) resorcinol dimethyl ether (1,3) - dimethoxybenzene)
4. Arrange the compounds of each set in order of reactivity toward bromine:
(a) anisole, benzene, chlorobenzene, Nitrobenzene, phenol
(b) anisole, m - hydroxyanisole, o - methylanisole, m - methylanisole
(c) p - C6H4 (OH) 2, p - CH3OC6H4OH, p - C6H4 (OCH3) 25 for each
Methyl tert-butyl ether is prepared, and a stream of hydrocarbons containing isobutylene is freed therefrom, by reacting the isobutylene with methanol in a two stage process wherein, in the first stage, a stream of hydrocarbons containing isobutylene and methanol is fed to a primary reaction zone where the isobutylene .
