Chemistry · Aldehyde and Ketones: Nature of carbonyl group, nucleophilic addition to >C=O group, relative reactivities of aldehydes and ketones

The solubility of water decreases rapidly with the increase in the size of group

The solubility of water decreases rapidly with the increase in the size of groups attached to carbonyl group.

  • A. alkyl
  • B. aryl
  • C. phenyl
  • D. benzyl

Step-by-step solution

Solubility of carbonyl compounds (aldehydes and ketones) in water depends on hydrogen bonding. As the size of the alkyl groups attached to the carbonyl carbon increases, the hydrocarbon character increases, reducing the ability to form hydrogen bonds with water, thus solubility decreases rapidly.
