Which type of bond results when more than one pair of electrons is shared?

When atoms form bonds by sharing electrons, the type of bond that results from the sharing of more than one pair of electrons is classified as a double bond or a triple bond. A single bond, for instance, involves the sharing of just one pair of electrons between two atoms. In contrast, double bonds involve the sharing of two pairs of electrons, while triple bonds consist of three pairs being shared.

Both double and triple bonds strengthen the connection between the bonded atoms compared to single bonds, leading to shorter and stronger interactions. For instance, in a molecule like oxygen (O₂), a double bond exists because each oxygen atom shares two pairs of electrons, which helps stabilize the molecule. In nitrogen gas (N₂), a triple bond forms by sharing three pairs of electrons, further increasing the bond strength and stability.

In summary, options that refer to a single bond or quadrapule bonds are not correct in this context, as they do not encompass the scenario of sharing more than one pair of electrons. The definition of covalent bonds is broader, encompassing all kinds of electron sharing, but does not specifically highlight the situation where multiple pairs are shared, which is why double or triple bonds are the appropriate answer for this question.
