Explanation:
Detailed explanation-1: -The increasing order of electronegativity of halogens is; I < Br < Cl < F .
Detailed explanation-2: -Electronegativity decreases in a group on going from top to bottom. Therefore increasing electronegativity order is I < Br < Cl < F.
Detailed explanation-3: -Electronegativity values increase in period 2 in the order C < N < O < F. Electronegativity values decrease from top to bottom within a group of elements. We will often use these periodic trends to interpret the chemical and physical properties of organic compounds.
