Aldehydes and ketones are pivotal organic compounds with a carbonyl group, influencing their structure and reactivity. Aldehydes have at least one hydrogen atom attached to the carbonyl carbon, while ketones feature two carbon-containing groups. Their oxidation from alcohols, distinct physical properties due to polarity, and susceptibility to nucleophilic addition reactions make them vital in organic chemistry and industrial applications.

The process of converting alcohols to aldehydes and ketones, crucial in various biochemical pathways and industrial applications
Primary alcohols oxidize to form aldehydes, which can further oxidize to carboxylic acids under more vigorous conditions
Secondary alcohols oxidize to form ketones, which are generally resistant to further oxidation under mild conditions
The naming system for aldehydes and ketones, governed by the International Union of Pure and Applied Chemistry
Aldehydes are named by replacing the '-e' ending of the corresponding alkane with '-al', and the carbonyl carbon is always considered to be carbon 1
Ketones are named by replacing the '-e' ending of the alkane with '-one' and numbering the chain such that the carbonyl carbon receives the lowest possible number
The susceptibility of the carbonyl carbon to nucleophilic attack, central to many reactions in organic chemistry
A reaction where nucleophiles add to the carbonyl carbon, crucial in the synthesis of a wide array of organic compounds
Aldehydes and ketones are widely used in various industrial processes, demonstrating their versatility as precursors to more complex organic molecules
