Ionic Character | MCQs

Explanation

Ionic character is determined by the difference in electronegativity between the atoms in a bond.

A larger electronegativity difference indicates a greater degree of ionic character.

CsF has the largest electronegativity difference due to the extremely high electronegativity of fluorine and the very low electronegativity of cesium. 

Explanation

HF has the highest ionic character

because electronegativity difference between H and F is highest.

ionic character follows the order HF >HCl>HBr> HI.

As the electronegativity difference increases ionic character increases.
