Question

Which among the following is the most reactive? (A) Cl2 (B) Br2 (C) I2 (D) ICl

Tardigrade Admin · Accepted Answer

ICl is an interhalogen compound. It contains two atoms of different electronegativities. Hence, the bond is polar. The molecules of chlorine bromine and iodine contain atoms of same electronegativity and they contain non polar bonds. Hence, ICl is most reactive.
