Question

The electronegativities of F, Cl, Br and 1 are 4.0, 3.0, 2.8, 2.5 respectively. Hydrogen halide with a high percentage of ionic character is (A) HF (B) HCl (C) HBr (D) HI

Tardigrade Admin · Accepted Answer

Greater is the electronegativity difference between X and H; the greater is the ionic character. Thus ionic character of H-F is maximum.

Q. The electronegativities of F,Cl,Br and 1 are 4.0,3.0,2.8,2.5 respectively. Hydrogen halide with a high percentage of ionic character is

HF

HCl

HBr

HI

Greater is the electronegativity difference between X and H; the greater is the ionic character. Thus ionic character of H-F is maximum.
