Answer:
POLAR
> a covalent bond is formed when two atoms SHARE electrons
(conversely, an ionic bond is when one atom donates an electron to another, more electronegative, atom)
> when there is an UNEVEN distribution of electrons/ electrons are NOT shared equally, then you have a POLAR bond where the CHARGE is not evenly distributed
(resulting in partial positive and negative sides of the molecule.. net dipole)
> POLAR covalent bonds form when there is a greater difference in electronegativity (some atoms have a greater desire to "grab" electrons to fill their octet and become more stable... for example H-F is a polar covalent bond)
