MCQ
Which among the following is the most reactive ?
  • A
    $I_2$
  • ✓
    $ICl$
  • C
    $Cl_2$
  • D
    $Br_2$
✓

Answer

Correct option: B.
$ICl$
b
$ICl$ 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.
