True or False: A polar bond is formed when electrons are shared equally between two atoms.

True or False: A polar bond is formed when electrons are shared equally between two atoms.

• A. True
• B. False
• C. Sometimes true
• D. Always true

Answer: (B)

A polar bond is characterized by an unequal sharing of electrons between two atoms, typically due to a difference in electronegativity. When two atoms have significantly different electronegativities, the atom with the higher electronegativity attracts the shared electrons more strongly, resulting in a partial negative charge on that atom and a partial positive charge on the other atom. This difference in charge distribution leads to a bond that is not purely covalent (where electrons are shared equally) but instead polar. Therefore, the statement that a polar bond is formed when electrons are shared equally is false, reinforcing that a polar bond specifically involves an unequal sharing of electrons.
