Which of the following factors does not explain why carbon can form so many compounds? a. carbon can bond in chains and rings. b. the same atoms can be grouped in different ways, forming isomers. c. carbon can form four single bonds. d. carbon has six protons in its nucleus.

d. Carbon has six protons in its nucleus.

Explanation:

Even if that is true, the fact that Carbon has 6 protons in its nucleus doesn´t provide any information on why does Carbon can form so many compounds, Carbon can form so many compounds because of the complexity and capability of its electrons on the outer shell to bond in different ways they can form isomers, the can form single bonds, they can be arranged in chains and rings, but the 6 protons in the nucleus doesn´t explain why Carbon can form so many compounds.
