Question

The three-dimensional structure of macromolecules is formed and maintained primarily through noncovalent interactions. Which one of the following is not considered a noncovalent interaction?A) carbon-carbon bondsB) hydrogen bondsC) hydrophobic interactionsD) ionic interactionsE) van der Waals interactions

Answer 1

carbon-carbon bonds.

Step-by-step explanation:

The non-covalent bonds are not formed by the sharing of electrons between the bonded atoms. These bonds may be formed by some electrostatic attraction between the oppositely charged atoms or any other type of interaction. However, the carbon-carbon bonds are formed when there is a sharing of electrons between the two atoms of carbon. Each carbon atom has four electrons available for bonding. Two carbon atoms share their electrons to complete the stable configuration of the presence of eight electrons in the outer most shell. Therefore, carbon bonds are covalent bonds.
