The more electronegative atom will make its end of the bond more negative.

The more electronegative an atom is the more "pull" the atom will have on the electrons in the molecules. For example, water (H2O) contains the very electronegative atom Oxygen. Oxygen would pull more electrons toward it so the hydrogen would essentially lose their electrons. The dipole moment would point towards the oxygen. Therefore, the more electronegative an atom is the more the dipole moment will point in its direction therefore affecting polarity of the bond.

The pair of atoms with the greatest polarity is oxygen and hydrogen. This is because oxygen is more electronegative than hydrogen, causing electrons to be unequally shared in the bond, resulting in a strong dipole moment.
Differences of polarity between different compounds (molecules) have two causes: - differences of asymmetry between these molecules - differences between the electronegativity of the atoms contained in the molecule
The cause of polarity of a covalent bond is the difference in electronegativity between the atoms being bonded. The more electronegative atom involved in the bond attracts the electrons more than the less electronegative. If you want to know the reason for electronegativity then follow the link.

The polarity of a water molecule is due to its asymmetric shape, with the oxygen atom being more electronegative than the hydrogen atoms. This causes a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms, creating a polar covalent bond.
Germanium bromide has a polar covalent bond because germanium is less electronegative than bromine. This results in an unequal sharing of electrons between the two atoms, making the molecule polar.

Chlorine does not form hydrogen bonds because it lacks hydrogen atoms that are necessary to establish these bonds. Hydrogen bonds occur between hydrogen atoms and electronegative atoms like oxygen, nitrogen, or fluorine. Chlorine is not electronegative enough to participate in hydrogen bond formation.
Water (H2O) is bonded through polar covalent bonds between the hydrogen atoms and the oxygen atom. The oxygen atom is more electronegative than the hydrogen atoms, causing a partial negative charge on oxygen and a partial positive charge on the hydrogen atoms. This polarity results in hydrogen bonding between adjacent water molecules.
