Because Cl is electronegative in nature and attracts bonded pair of elecrons.

HCl is a polar covalent compound because in this H+ is a proton having electron affinity and having the tendency to gain the electron but Cl- is act like an anion and having tendency to donate the electron and Cl- is a electronegative atom and as the H+ comes close to Cl- anion then negative charge spreads...

HCl is a polar covalent compound because in this H+ is a proton having electron affinity and having the tendency to gain the electron but Cl- is act like an anion and having tendency to donate the electron and Cl- is a electronegative atom and as the H+ comes close to Cl- anion then negative charge spreads and polarity begins according to Fazan's Rule and due to this two shared pair electrons of Cl- make the covalent bond with H+ (both the electrons in covalent bond is from Cl- atom. HCl is also called it as hetro-atomic molecule. read less

Due to the higher electronegativity of chlorine than hydrogen. Chlorine attract the electron towards itself and becomes polar.

Hydrogen has an electronegativity of 2.1, and chlorine has an electronegativity of 3.0. The electron pair that is bonding HCl together shifts toward the chlorine atom because it has a larger electronegativity value. A bond in which the electron pair is shifted toward one atom is called a polar covalent...

Electronegativity of chlorine is greater than hydrogen atom so far center of gravity of all positive ions sifted towards the hydrogen atom and Center of gravity of all negative ions shifted to chlorine atom and electric dipole form in clorine. Hence HCl have polar substance

The electron pair that is bonding HCl together shifts towards Cl atom as Cl is highly electronegative. A bond in which the electron pair is shifted towards one atom is called a polar covalent bond.

Due to higher electronegativity of Cl, the electron pair binding the H and Cl shifts towards Cl. And a bond in which electron pair is shifted towards one atom is known as polar covalent bond that is why it's a polar covalent compound.

The covalent bond means the mutual sharing of electron from the atom, in HCl the H atom is shared one electron from 1s orbital and Cl atom sharing one electron from its 3p orbital form a covlant bond. this bond is polar because of the difference in electronagativity of Hydrogen atom and Chlorine atom...

The covalent bond means the mutual sharing of electron from the atom, in HCl the H atom is shared one electron from 1s orbital and Cl atom sharing one electron from its 3p orbital form a covlant bond. this bond is polar because of the difference in electronagativity of Hydrogen atom and Chlorine atom Hydrogen having electronegativity is 2.20 and Chlorine having electronegativity is 3.16, because of more electronagativity of chlorine it full more electron density from hydrogen in HCl molecule the electronegativity difference is greater than 1.5 is purely ionic but in HCL its electronegativity difference is about 0.96 it is lower than 1.5 so for that it is covalant compoud but more electron density present in Cl atom because of chlorine is more electronegative than hydrogen so it is having polar covalent bond and for that it is polar covalent compound. read less

Polarity results from unequal sharing of valance electron. That is Cl pulls electron towards itself & it carries carry partial negative charge. While H carries partial positive charge & this makes HCl polar.
