J & K CETJ & K CET 2009Aldehydes Ketones and Carboxylic Acids

Solution:

## Crystalline solid derivatives are formed when aldehydes or ketones are shaken with saturated aqueous solution of sodium bisulphite, but sodium bisulphite is a bigger nucleophile so, all ketones do not give this test. Only aliphatic methyl ketones form addition product with sodium bisulphite.
