Hydrogen bonding

Vedclass · Answer

(B) . The solubility of lower alcohols like methanol $(CH_3OH)$ and ethanol $(C_2H_5OH)$ in water is due to their ability to form intermolecular hydrogen bonds with water molecules.
The oxygen atom of the alcohol group carries a partial negative charge $(\delta-)$ and the hydrogen atom carries a partial positive charge $(\delta+)$,allowing them to interact with the water molecules through hydrogen bonding: $R-O^{\delta-}-H^{\delta+} \dots O^{\delta-}(H)-H^{\delta+}$.
Thus,option $B$ is correct.
