Dear Student,

 

Hydrogen choride is a polar covalent compound due to difference in the electronegativities of bonding atoms. Hydrogen is electropositive while chlorine is electronegative, hence even though the bond is formed by sharing of electrons (one electrons each from hydrogen and chlorine atoms), the bonding pair of electrons get shifted more towards more electronegative chlorineatom forming delta negative charge on it while hydrogen due to lack of electrons form delta positive charge. Thus in aqueous solution, HCl can easily form H⁺ and Cl^- ions. But it is still a polar covalent compound and not an ionic compound which is formed by donation of electrons from cation to anion.

 

Thanks and Regards
