Electronegativity values:
Oxygen (O): 3.44
Fluorine (F): 3.98
Electronegativity difference = |3.98 - 3.44| = 0.54
Based on the electronegativity difference, OF2 has a polar covalent bond. This means that the electrons in the O-F bonds are shared unequally, with fluorine atoms having a slight negative charge and oxygen atoms having a slight positive charge. This polarity in the bond arises due to the difference in electronegativity between oxygen and fluorine.
