Question

Arrange the interactions between pairs of electrons in order of increasing strength.
A)bonding pair-bonding pair < lone pair-bonding pair < lone pair-lone pair
B)bonding pair-bonding pair <  lone pair-lone pair < lone pair-bonding pair
C)lone pair-lone pair < lone pair-bonding pair < bonding pair-bonding pair
D)lone pair-lone pair < bonding pair-bonding pair < lone pair-bonding pair
E)lone pair-bonding pair < bonding pair-bonding pair < lone pair-lone pair

Quizplus · Accepted Answer

The strength of the interaction between pairs of electrons increases as the number of electrons in the orbitals involved increases. Bonding pairs have two electrons, lone pairs have one electron, and sigma bonds have one electron. Therefore, the order of increasing strength is lone pair-lone pair < lone pair-bonding pair < bonding pair-bonding pair.
