We have to determine whether BrF5 is a polar molecule or not.
Molecular polarity is a result of polar covalent bonds in the molecule. A covalent bond is polar when there is a difference of electronegativity between the two atoms forming the bond.
For example, the electronegativity of hydrogen is 2.1 and that of oxygen is 3.5. A bond between H and O will be polar due to the difference in electronegativity.
A polar bond is a dipole. The more electronegative atom acquires a partial negative charge while the less electronegative atom acquires a partial positive charge.
Determine whether each molecule is polar or nonpolar.
