Question

A polar bond is a covalent bond in which there is an electronegativity difference between the two bonded atoms and electrons are shared unequally. The atom with the higher electronegativity will have a partial _____ charge and is marked with the symbol _____ while the atom with the lower electronegativity will have a partial _____ charge and is marked with the symbol _____.

A. negative; δ-, positive; δ+
B. positive; δ+; negative; δ-
C. negative; δ+; positive; δ-
D. positive; δ-; negative; δ+

Answer 1

In a polar covalent bond, the atom with the higher electronegativity will have a partial negative charge (δ-) and the atom with the lower electronegativity will have a partial positive charge (δ+).

Step-by-step explanation:

In a polar covalent bond, the atom with the higher electronegativity will have a partial negative charge and is marked with the symbol δ-, while the atom with the lower electronegativity will have a partial positive charge and is marked with the symbol δ+.

For example, in a hydrogen chloride (HCl) molecule, the chlorine atom has a higher electronegativity and carries a partial negative charge (δ-), while the hydrogen atom has a lower electronegativity and carries a partial positive charge (δ+).
