Question

both alcohol and phenol contain hydroxyl group but alcohol undergoes esterification, phenol does not. Explain​

Answer 1

Alcohols and phenols

An oxygen atom normally forms two σ bonds with other atoms; the water molecule, H2O, is the simplest and most common example. If one hydrogen atom is removed from a water molecule, a hydroxyl functional group (―OH) is generated. When a hydroxyl group is joined to an alkane framework, an alcohol such as ethanol, is produced.

Chemical Compound. Structural formulas for ethanol, ehylene glycol, phenol, and vitamin E.

When the hydroxyl group is joined to an aryl ring, a phenol results (shown above). Both alcohols and phenols are widespread in nature, with alcohols being especially ubiquitous. The hydroxyl group of alcohols and phenols is responsible for an interesting variety of physical and chemical properties. The biochemical action of vitamin E, for example, depends largely on the reactivity of the phenol functional group.
