ketoonrühmast

Ketoonrühmast refers to the carbonyl group (C=O) when it is part of a ketone molecule. This functional group is characterized by a carbon atom double-bonded to an oxygen atom. In ketones, this carbonyl group is situated between two alkyl or aryl groups. The presence of the highly electronegative oxygen atom makes the carbonyl carbon electrophilic, susceptible to nucleophilic attack. This reactivity is fundamental to many organic reactions involving ketones, such as addition reactions, nucleophilic acyl substitution (though less common for ketones compared to carboxylic acid derivatives), and condensation reactions. Ketones are important in organic chemistry as intermediates in synthesis and are found in various natural products and pharmaceuticals. Their physical properties, such as boiling point and solubility, are influenced by the polarity of the carbonyl group.
