WebIron (III) chloride, or ferric chloride, forms a brown complex when it's dissolved in water. If you add a phenol to this solution, a purple iron (III)-phenol complex will form instead. This effect is not observed with non-aromatic or aliphatic alcohols. Put on a lab coat, safety glasses, and gloves before you begin. WebAlkoxides, the conjugate bases of alcohols, are prepared from alcohols by reaction with reactive metals or metal hydrides. They are used as organic bases. Because of the greater acidity of phenols, phenoxides can be obtained from phenols and aqueous base. Alcohols and phenols are also weak bases. They can be protonated on the oxygen by strong ...
