Question

Какая из связей в молекуле пропанола-1 наиболее полярна и почему?

Answer 1

Самая полярная связь в пропаноле О-Н  Кислород стягивает всю электронную плотность на себя, в следствие его высокой электроотрицательности. 

Answer 2

The Most Polar Bond in Propanol-1 Molecule

The most polar bond in the propanol-1 molecule is the bond between the oxygen atom and the hydrogen atom in the hydroxyl group (OH). This bond is the most polar because oxygen is more electronegative than hydrogen, meaning it has a greater ability to attract electrons towards itself. As a result, the oxygen atom in the hydroxyl group has a partial negative charge (δ-) while the hydrogen atom has a partial positive charge (δ+). This separation of charges creates a dipole moment, making the oxygen-hydrogen bond in the hydroxyl group the most polar bond in the propanol-1 molecule.
