Question

Which of the following is not true of polar covalent bonds? (PF)

A. Polar covalent bonds exist between atoms of the same element.
B. Polar covalent bonds create two poles across the bond.
C. Polar covalent bonds result from the unequal sharing of electrons.
D. Electronegativity differences for atoms with polar covalent bonds range between 0.5 and 2.0

Answer 1

Answer:

A. Polar covalent bonds exist between atoms of the same element.

Explanation:

Because we have a bond between the two atoms of the same element, the difference of the electronegativity between two elements is zero thus the electron density is equally shared by the atoms so the bond will be a non-polar covalent one.
