* Presence of a hydroxyl group (OH): The hydroxyl group is highly polar due to the electronegativity difference between oxygen and hydrogen. Oxygen is more electronegative, pulling electron density towards itself, creating a partial negative charge (δ-) on the oxygen and a partial positive charge (δ+) on the hydrogen.
* Molecular shape: The molecule has a bent shape around the oxygen atom, which further enhances the polarity. This bent shape prevents the dipole moments from cancelling each other out, resulting in a net dipole moment.
* Hydrogen bonding: The polar hydroxyl group allows 2-propanol to form hydrogen bonds with other 2-propanol molecules or with other polar molecules, contributing to its overall polarity.
Overall, the presence of the polar hydroxyl group, the bent shape of the molecule, and the ability to form hydrogen bonds contribute to the polar nature of 2-propanol.
