Statement-I : Aldehyde (or) ketone sodium bisulphite when treated with dil mineral acid (or) alkali regenerates pure aldehyde (or) ketoneStatement-II : Ketals (or) acetals get hydrolysed with aqueous mineral acids to give ketones (or) aldehydes.

I)The product obtained when treated with dilute acid (or) alkali 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.This reaction is given by aliphatic aldehydes and methyl ketones only. II) R-CHOR2 is a acetal and R2COR2 is a ketal ; R-CHOR2→H3O+R-CHO+2R-OH ; Similarly ketals also give ketones;
