Solution:
The lower aldehydes have sharp pungent odours. As the size of the molecule increases, the odour becomes less pungent and more fragrant.
The solubility of aldehyde and ketones decreases rapidly on increasing the length of the alkyl chain. All aldehyde and ketones are fairly soluble in organic solvents like benzene, ether, mathanol, chloroform etc.
