Why halogens act as oxidising agents?

Text Solution

Verified by Experts

Halogens act as oxidizing agents. Their electronic configuration is `ns^2 np^5`. So all the halogens are ready to gain one electron to attain the nearest inert gas configuration. An oxidizing agent is the one which is ready to gain an electron. So all the halogens act as oxidizing agents. Also halogens are highly electronegative with low dissociation energy and high negative electron gain enthalpies. Therefore, the halogens have a high tendency to gain an electron. Hence they act as oxidizing agents.
