# Question #00965

Oxygen would have the $\delta -$, it is more electronegative than is Boron (if we are considering a B-O bond, perhaps).
Oxygen would have the $\delta -$, it is more electronegative than is Boron, the electrons will be closer to it than they are to Boron in the hypothetical chemical species.
Due to the greater electronegativity of oxygen, the electron will be unequally shared about the chemical species (with more residing closer to oxygen) and this will lead to a $\delta -$ about the $O$ species and a $\delta +$ about the species $B$.
