The atom that acquires the most negative charge in a covalent bond with hydrogen is the atom with higher electronegativity. In most cases, this is the atom from the upper right corner of the periodic table, such as oxygen, nitrogen, or halogens like fluorine and chlorine.
The atom that attracts electrons more strongly will acquire a partial negative charge in a covalent bond with hydrogen. This can be determined by looking at the electronegativity values of the atoms involved in the bond; the atom with the higher electronegativity will acquire the most negative charge.
Hydrogen chloride (HCl) is a polar covalent molecule because it has a significant difference in electronegativity between the hydrogen and chlorine atoms. Chlorine is more electronegative, meaning it has a stronger attraction for electrons, causing the shared electron pair between hydrogen and chlorine to be unequally shared. As a result, the chlorine atom acquires a partial negative charge, while the hydrogen atom acquires a partial positive charge. This uneven distribution of charge creates a dipole moment, making HCl a polar covalent molecule.
A negative charge that exists because of a covalent bond with hydrogen
NH3 is a polar covalent molecule. It is formed by sharing electrons between nitrogen and hydrogen atoms, resulting in a partial positive charge on hydrogen atoms and a partial negative charge on the nitrogen atom.

Check the electronegatviies of the atoms. The highest from the top are fluorine, oxygen, chlorine and nitrogen. The highest electronegativity pulls the electrons in the bond closest, gets the most negative charge.

A negative charge exists because of the electronegativity of oxygen.
A negative charge that exists because of a covalent bond with hydrogen
NH3 is a polar covalent molecule. It is formed by sharing electrons between nitrogen and hydrogen atoms, resulting in a partial positive charge on hydrogen atoms and a partial negative charge on the nitrogen atom.
Hydrogen chloride is held together by a polar covalent bond where the hydrogen atom shares its electron with the chlorine atom, resulting in a partial positive charge on hydrogen and a partial negative charge on chlorine.
Hydrogen bonds and covalent bonds are two completely different things. Covalent bonds share an electron, while hydrogen bonds (just for water molecules) act like magnets- the Oxygen atom has a slight negative charge and it "attracts" the Hydrogen atoms, which have a slight positive charge.
a positive charge caused by a covalent bond with oxygen
HBr is a polar covalent molecule. The electronegativity difference between hydrogen and bromine causes an unequal sharing of electrons, resulting in a partial positive charge on hydrogen and a partial negative charge on bromine.
CH3OH is a polar covalent molecule. This is because there is a significant difference in electronegativity between carbon, oxygen, and hydrogen atoms in the molecule, resulting in a partial positive charge on hydrogen and a partial negative charge on oxygen.
