Question

Hey guys plzz give correct answer​

Answer 1

d) INCORRECT -

Electronegativity decreases on moving down the group because size of atom increases. Decreasing order of electro-negativity of halogens is F, Cl, Br, I. Fluorine has highest electronegativity among all the known elements.

Hence, it's correct order should be,

F > Cl > Br > I

Hope it helps.
