Concept Introduction:
Acetals are geminal diol or diether derivatives of aldehydes or ketones, formed by the reversible addition of two moles of water or alcohol to the carbonyl group in acidic conditions.
Hydrolysis of a cyclic acetal in acidic conditions yields the original carbonyl compound and a diol.
Ketones reversibly undergo enolization in aqueous solutions. If the enolization leads to aromatiziation, the higher stability of aromatic ring can drive the isomerization to complete enolization.
