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 interactions

The correct answer is A) carbon-carbon bonds.

Explanation:

The noncovalent interactions can generally be classified into electrostatic, π interactions, Van der Waals forces, and hydrophobic interactions. They do not share electrons, but present more dispersed variations of electromagnetic interactions between molecules or within the same molecule.

In a carbon-carbon bond, there is a covalent bond between two atoms in an organic compound. The most common form is the simple bond, which is composed of two electrons, one belonging to each of the two atoms. The simple carbon-carbon bond is a sigma bond.

Have a nice day!

The correct option is A

Explanation:

Non-covalent interactions, from the name, means interactions that do not involve covalent interaction. Covalent interaction involves the sharing of electrons between two atoms. The bond between two carbons in organic compounds is covalent bond. The covalent interaction in itself does not permit for three-dimensional structure. Examples of noncovalent interaction include hydrogen bonds, ionic interactions, van der waals interactions and hydrogen bonds
