C-Cl bond is greater polar than C-Br bond.the polarity of any bond relies upon on the electronegativity distinction of the climate constituting the bond.greater suitable is the version greater is the polarity of bond.here in the two bonds carbon atom is comparable yet chlorine is greater electronegative than bromine so C-Cl is greater polar than C-Br.
