All of the following are incorrect statements regarding difference between polar and non-polar bonds EXCEPT:
Correct answer: C. (1). A polar covalent bond can have polarity.(2). A non polar covalent bond can have no polarity.
- A. (1)A non polar covalent bond is a type of covalent bond in which the two atoms share electrons unequally(2)In a polar covalent bond, the two atoms have the same electronegativity. The electrons in the bond are therefore shared equally between the two atoms, and there is no partial positive or negative charge on either atom.
- B. (1).Polar covalent bonds are formed between atoms that have the same electronegativity.(2).Non-polar covalent bonds are formed between atoms that have the difference in electronegativity.
- C. (1). A polar covalent bond can have polarity.(2). A non polar covalent bond can have no polarity.
- D. None of these
Explanation
Option C is correct.A polar covalent bond cannot have no polarity. A polar covalent bond is a type of covalent bond in which the electrons are shared unequally between the two bonded atoms. This is because the two atoms have different electronegativities, which is a measure of how strongly each atom attracts electrons. The more electronegative atom will have a greater pull on the shared electrons, resulting in a partial negative charge on that atom and a partial positive charge on the other atom.A bond with no polarity would be a nonpolar covalent bond, which occurs when the two bonded atoms have the same electronegativity. In this case, the electrons are shared equally between the two atoms, and there is no net dipole moment.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
