Question:
Assertion (A): The solubility of aldehydes and ketones in water decreases with increase in size of the alkyl group.
Reason (R): Aldehydes and ketones have dipole-dipole interaction.
Assertion (A): The solubility of aldehydes and ketones in water decreases with increase in size of the alkyl group.
Reason (R): Aldehydes and ketones have dipole-dipole interaction.
Reason (R): Aldehydes and ketones have dipole-dipole interaction.
Show Hint
The polarity of the carbonyl group in aldehydes and ketones decreases with the increase in size of the alkyl group, reducing their solubility in water.

- Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
- Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
- Assertion (A) is true, but Reason (R) is false.
- Assertion (A) is false, but Reason (R) is true.
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
As the alkyl group size in aldehydes and ketones increases, the non-polar nature of the alkyl group dominates, reducing the interaction of the carbonyl group with water molecules. This leads to decreased solubility in water. Reason (R) explains Assertion (A) correctly as aldehydes and ketones do indeed experience dipole-dipole interactions.

- Carbohydrates are polyhydroxy aldehydes or ketones that represent enormous structural diversity in terms of the arrangement of atoms in space, resulting in hundreds of stereoisomers. Although the chemical properties of most stereoisomers may not be very different, their metabolic rate and utilization in biological systems is significantly different and known to influence the overall carbohydrate metabolism. Structural variants, which arise due to a different arrangement of atoms in three-dimensional space are known as stereoisomers. The number of stereoisomers can be theoretically estimated by using the formula 2n, where ‘n’ is the number of stereocenters or asymmetric (chiral) carbon atoms in a molecule. Out of these stereoisomers, there are some structures, which are mirror images of each other, and they are referred to as enantiomers.
