Isomers of alcohol having a molecular formula C 4 H 10 O that can be prepared from the reduction of aldehydes and ketones respectively are to be determined. The isomeric form of the same alcohol that cannot be prepared form the reduction of any carbonyl compound is to be identified. Concept introduction: The isomers are associated with the same chemical formula but have different connectivity of atoms. The aldehyde or ketone on hydrogenation undergoes addition of hydrogen across the carbon-oxygen double bond and forms corresponding alcohol. Hydrogenation is basically the reduction process. The primary alcohol is obtained after reduction of aldehydes, the ketones on reduction gave secondary alcohol but no carbonyl compound gave tertiary alcohol after the reduction process.

Question

Which of the isomeric C4H₁0O alcohols can be prepared by hydrogenation of aldehydes? Which can be prepared by hydrogenation of ketones? Which cannot be prepared by hydrogenation of a carbonyl compound?

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
