In UAE butanone lialh4

Oxidation of Butanol: Easy exam revision notes for GSCE Chemistry

In this reaction the butanol is oxidised to butanal by removing two hydrogen atoms. The aldehyde needs to be removed from the reaction mixture as soon as possible otherwise the resulting aldehyde can undergo further oxidation to a carboxylic acid. This is done by using an excess of alcohol and distilling off the aldehyde as soon as it forms.

    17.4: Alcohols from Carbonyl Compounds- Reduction

    24/9/2022· Both NaBH 4 and LiAlH 4 act as if they were a source of the hydride anion nucleophile. They hydride anion undergoes nucleophilic addition to the carbonyl carbon to form a C-H single bond and forming a tetrahedral alkoxide ion intermediate. The alkoxide ion is subsequently converted to an alcohol by reaction with a proton source.
