The equilibrium lies towards------------ for aldehyde and lies towards---------- for ketones

The product obtained when treated with dilute acids (or) alkalies regenerates pure carbonyl compounds. In the reaction involving aldehydes, equilibrium will be shifting towards rightIn the reaction involving ketones, equilibrium will be shifting towards left;Lesser reactivity of ketones is due to +I effect of alkyl groups and steric hindrance;This reaction is given by aliphatic aldehydes and methyl ketones only.
