Question

Statement I Solubility of ^-alcohol in water decreases with increase in molecular weight.
Statement II The relative proportion of the hydrocarbon part in alcohols increases with increasing molecular weight
which permit enhanced hydrogen bonding with water.
(1) Statement I is correct; Statement II is correct; Statement II is a correct explanation of Statement I.
(2) Statement I is correct; Statement II is correct; Statement II is not the correct explanation of Statement I
(3) Statement I is correct; Statement II is incorrect.
(4) Statement I is incorrect; Statement II is correct.

Answer 1

$\underset{\text{Hydrophobic}}{R-OH\leftarrow \text{Hydrophilic}}$
Increasing molecular weight increases hydrocarbon $(R)$ proportion that lowers the solubility in water.
