Alcohols — practice question
The diagram represents several reactions of butanol. At the centre is butanol, $\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{OH}$. When complete combustion occurs, gas A and liquid B are formed. When combustion is incomplete, liquid B and gas C are formed. Oxidation with acidified potassium manganate(VII) gives organic liquid D. Heating with ethanoic acid produces liquid B and organic liquid E.
