Here's why:
* Polar Covalent Bonds: The molecule contains carbonyl groups (C=O) and hydroxyl groups (O-H). These bonds have a significant difference in electronegativity between the oxygen and carbon/hydrogen atoms, creating a partial positive charge on the less electronegative atom and a partial negative charge on the oxygen. This makes these bonds polar.
* Nonpolar Covalent Bonds: The benzene ring and the ester group (C-O-C) have carbon-carbon and carbon-hydrogen bonds. These bonds have a very small difference in electronegativity, making them essentially nonpolar.
Therefore, phenyl salicylate is not simply a "polar covalent bond" molecule. It contains both polar and nonpolar covalent bonds. This makes the overall molecule polar, as the polar bonds contribute more to the overall dipole moment than the nonpolar bonds.
