Q. Which among the following is the most reactive?

JEE MainJEE Main 2015The p-Block Elements - Part2

Solution:

$ICl$ 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.
