Polar compounds are chemical compounds that are held together by polar covalent bonds. The term ‘polar compound’ can be defined as a chemical species which consists of two or more atoms that are held together by covalent bonds that are polar in nature due to the unequal sharing of electrons. When two atoms are bound together via a covalent bond the differences in the electronegativities of the bonded atoms may cause the bond pair of electrons to shift closer to the more electronegative atom. This results in the accumulation of a partial positive charge at the location of the more electropositive atom and the accumulation of a partial negative charge at the location of the more electronegative atom. Polar compounds are chemical compounds that are held together by such bonds.
In the bond dipole vector of C−F bond is not subtractive.
