Carboxylic acids have higher boiling points than aldehydes, ketones and even alcohols of comparable molecular mass. It is due to their
1 More extensive association of carboxylic acid via vander Waals force of attraction.
2 Formation of intermolecular hydrogen bonding
3 Formation of carboxylate ion
4 Formation of intramolecular hydrogen bonding
Explanation:
Carboxylic acids have quite high boiling points due to the presence of intermolecular hydrogen bonding which results in the formation of dimeric structure.

Lower members of aliphatic carboxylic acids are soluble in water. This is due to
1 Formation of hydrogen bonds with water
2 London forces
3 Water is non-electrolyte
4 van der Waal's interaction with water molecules.
Explanation:
Due to the formation of H-bonding with water.

Assertion : First four aliphatic monocarboxylic acids are colourless. Reason : Carboxylic acids with more than five carbon atoms are insoluble in water.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Carboxylic acids are soluble in water due to hydrogen bonding between the \(-\mathrm{COOH}\) group and water molecules. But increased hydrophobicity from larger alkyl (-R) groups, especially beyond five carbon atoms, reduces solubility. So the option (2) is correct.

Assertion : cis-3-Chloroprop-2-enoic acid is less stable than its trans-form. Reason : Dipole moment of cis-form is greater than trans-form.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
In acrylic systems, trans isomers prevail due to decreased steric hindrance and minimal dipole moments, rendering them more stable and less polar compared to cis isomers. So the option (2) is correct.
