preparation of phenols from haloarenes

Chlorobenzene (an haloarene) is hydrolysed by treating it with 10% NaOH at 623 K and 320 atmospheric pressure in presence of Cu catalyst. Phenol is obtained by acidification of sodium phenoxide...

A trihydric alcohol, glycerol is a constituent of oils and fats. Oils and fats are tri esters of long chain fatty acids. On hydrolosys in presence of an alkali, the tri esters yield glycerol and the fall of the carboxylic acids. ..

The reactivity of haloarenes is markedly affected by the presence of certain groups at certain positions of the ring. The presence of electron withdrawing groups such as -NO 2 , -CN, -COOH, etc. at 'o' and 'p' positions to the halogen atom, greatly activates the halogen towards nucleop..

Preparation of Phenols - In the early nineteenth century, phenol was selected from coal tar by destructive distillation. Now phenol is commercially produced synthetically. The laboratory methods of preparation of phenols a..

Phenols turn blue litmus red and react with metals liberating hydrogen. However they do not react with carbonates or bicarbonates. Phenols behave as acids because of the presence of polar O-H group in them. They ionise in aqueous solutions to give H + ion..
