HCl is a polar molecule with the hydrogen part being partial positive while the chlorine end being partial negative. This is because hydrogen has an electronegativity of 2.1, and chlorine has an electronegativity of 3.0. This means that chlorine attracted most of the electron cloud of molecule hence is the negative dipole, The dipole moment of HCl is 1.08 D (debyes). A Debye is equal to 3.34 x 10-30 coulomb-meters (C-m). The charge of each molecule is o.176+ for H and 0.176- for the Cl
Hydrogen will develop a [tex]\boxed{{\text{positive}}}[/tex] charge and chlorine will acquire a [tex]\boxed{{\text{negative}}}[/tex] charge.

Covalent Bond:
The bond that is formed by the mutual sharing of electrons between the bonded atoms is called a covalent bond. It is also known as a molecular bond. Covalent compounds are those compounds which are formed by the electron sharing between two or more non-metals.
Following are some of the properties of covalent compounds:
1. These are brittle solids.
2. Low melting and boiling points.
3. Poor conductors of heat and electricity.
4. Low enthalpy of fusion.
Boron trichloride [tex]\left({{\text{BC}}{{\text{l}}_3}}\right)[/tex] , silicon dioxide [tex]\left({{\text{Si}}{{\text{O}}_2}}\right)[/tex] , and xenon hexafluoride [tex]\left({{\text{Xe}}{{\text{F}}_{\text{6}}}}\right)[/tex] are some examples of covalent compounds.
Both hydrogen and chlorine are non-metals and the bond formed between two non-metals is a covalent bond. So HCl is a covalent compound. Chlorine has 7 electrons in its valence shell and hydrogen has only one electron. Both share electrons in order to achieve the nearest stable electronic configuration of the noble gas. (Refer to the attached image)
Chlorine is more electronegative than hydrogen so it will attract electrons towards itself and thereby developing a negative charge, which in turn results in hydrogen having a positive charge. So chlorine end of HCl molecule is negatively charged while its hydrogen end is positively charged.
