Explain the intermolecular hydrogen bonding in alcohols and phenols and its effect on their physical properties.

(N/A) $1$. In alcohols and phenols,the oxygen atom of the $-OH$ group is highly electronegative,which creates a partial negative charge $(\delta^-)$ on the oxygen and a partial positive charge $(\delta^+)$ on the hydrogen atom.
$2$. This polarity leads to the formation of intermolecular hydrogen bonds between the hydrogen atom of one molecule and the oxygen atom of another molecule.
$3$. Effect on Physical Properties: Due to the presence of these intermolecular hydrogen bonds,alcohols and phenols exhibit higher boiling points compared to alkanes,ethers,or haloalkanes of comparable molecular masses.
$4$. Additionally,these hydrogen bonds allow alcohols and phenols to form hydrogen bonds with water molecules,which explains their solubility in water.
