polar covalent bonds occur because one atom is much more electronegative than the other right?
so..an example of a polar covalent bond is C-H ?

A polar covalent bond is a type of chemical bond where two atoms share electrons unequally. This creates a separation of charge within the molecule, with one end being slightly positive and the other slightly negative.
In a nonpolar covalent bond, the two atoms share electrons equally. This results in no separation of charge and a symmetrical distribution of electrons within the molecule. In a polar covalent bond, the electrons are shared unequally, leading to a separation of charge and an asymmetrical distribution of electrons.
The difference in electronegativity between the two atoms involved in the bond is the main factor that determines the polarity of a covalent bond. The greater the electronegativity difference, the more polar the bond will be.
Water (H2O) is a common example of a molecule with polar covalent bonds. Other examples include hydrogen fluoride (HF), ammonia (NH3), and hydrogen chloride (HCl).
The polarity of a covalent bond can affect the overall polarity of a molecule, as well as its boiling point, melting point, and solubility in different substances. Polar molecules tend to have higher boiling and melting points and are more likely to dissolve in polar solvents.
