Arrange the following in the increasingorder of the property indicated : (i) Benzoic acid, 4-Nitrobenzoic acid, 3,5-dinitrobenzoic acid, 4-Methoxybenzoic acid (acid strength) (ii) Acetaldehyde, Acetone , Di-tertbutylketone. Methylterbutyl keton ( Reactivity towards HCN ) . |

Answer» Solution :(i) The increassing order of acid strength is `:` 4-Methoxybenzoic acid `lt ` Benzoic acid `lt ` 4-Nitrobenzoic acid `lt ` 3,5-Dinitobenzoic acid (ii)  Smaller the steric hinderance to the nucleophile`CN^(-)` , GREATER will be the REACTIVITY. Hence, the reactivity towards HCN in increasing order will be  or Di-tertbutyl ketone `lt `Methylterbutyl ketone `lt ` ACETONE `lt `Acetaldehyde |
