Overview

Carbonyl compounds are important organic compounds found in fabrics, flavourings, plastics and drugs. The carbonyl group is >C=O, and it gives aldehydes, ketones and carboxylic acids their main properties and reactions. Aldehydes contain a carbonyl carbon bonded to carbon and hydrogen, ketones conta

Key Concepts

Aldehydes have the group RCHO

Aldehydes have the group RCHO, ketones have R2CO, and carboxylic acids have RCOOH or ArCOOH. Aldehydes are named with the suffix -al, ketones with -on

The carbonyl carbon is sp2

The carbonyl carbon is sp2-hybridised with bond angles of about 120°. The carbonyl bond is highly polar, so the carbonyl carbon is electrophilic and t

Aldehydes and ketones are prepared by

Aldehydes and ketones are prepared by oxidation or dehydrogenation of alcohols, ozonolysis of alkenes, hydration of alkynes, Rosenmund reduction, Step

A nucleophile attacks the electrophilic carbonyl

A nucleophile attacks the electrophilic carbonyl carbon, the hybridisation changes from sp2 to sp3, and a tetrahedral intermediate forms before proton

HCN gives cyanohydrins

HCN gives cyanohydrins, NaHSO3 gives bisulphite addition compounds, alcohols give hemiacetals and acetals or ketals, and ammonia or derivatives give i
