High percentage of ionic character results in the highest value of dipole moment in:

آئنک کیریکٹر کا اعلی فیصد ڈوپول لمحے کی بلند ترین قدر کا نتیجہ کس میں ہے

Hydrogen fluoride

Hydrogen chloride

Sulphur dioxide

Hydrogen disulphate

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.
