Answer:
Yes, the bonds of ammonia (NH3) are polar covalent. In a polar covalent bond, the electrons are not shared equally between the atoms involved in the bond, resulting in a partial positive and partial negative charge on the atoms. In the case of ammonia, the nitrogen atom is more electronegative than the hydrogen atoms, so it attracts the shared electrons more strongly towards itself. This creates a partial negative charge on the nitrogen atom and a partial positive charge on each hydrogen atom. This overall uneven distribution of electron density in the molecule makes ammonia polar.
