Assertion: Solubility of n-alcohol in wa...

Assertion: Solubility of `n`-alcohol in water decreases with increases in molar mass.
Reason: The hydrophobic neture of alky`1` chain increases.

A

If both assertion and reason are true and the reason is the correct explanantion of the assertion.

B

If both assertion and reason are true but reason is not the correct explanantion of the asseriton.

C

If assertion is true but reason is false.

D

If assertion if false but reason is ture.

Text Solution

Verified by Experts

The correct Answer is:
A
The solubility if alcohols in water is dut to `H-` bonding. As the molar mass of alcohol increases, the increase in hydrophobic nature of alky`1` group results in decrease in solubility.
