Lower members of aldehydes are soluble in water where as the higher – InterviewSolution

1.	Lower members of aldehydes are soluble in water where as the higher members are not. Give reasons.
Answer» Solution :The lower members are soluble in water, as the carbonyl group is polar and it can FORM intermolecular hydrogen BONDING with water. This .SOLUBILITY decreases with increase in the size of alkyl group. This is because BIGGER alkyl groups increase the non-polar character of the molecule and prevent hydrogen bonding with water.
