Which of the following statements best describes a relatively polar bond?
A)a very electronegative atom and a weakly electronegative atom are covalently bound
B)two very electronegative atoms are covalently bound
C)two very electronegative atoms undergo ionic bonding
D)two weakly electronegative atoms undergo ionic bonding
E)none of the above

Quizplus · Accepted Answer

A relatively polar bond occurs when there is a difference in electronegativity between the two atoms involved. In choice A, there is a large difference in electronegativity between the very electronegative atom and the weakly electronegative atom, leading to a relatively polar bond. In choice B, both atoms are very electronegative, which would likely lead to an ionic bond. Choice C describes an ionic bond between two very electronegative atoms, while choice D describes an ionic bond between two weakly electronegative atoms; neither option describes a relatively polar bond.
