Question

All living things contain carbon. Which of the following statements are true about carbon atoms? I. Each carbon atom can form single bonds with up to four other carbon atoms. II. Each carbon atom can form double bonds with up to two other carbon atoms. III. Carbon atoms can join together to form chains or rings. IV. A single molecule of some compounds can contain thousands of carbon atoms.

Answer 1

All four of the answers are right

Answer 2

All the given statements given about carbon are true.

Carbon is an element which has atomic number 6 and valency as 4. Thus, it can form 4 bonds at a time.

It can satisfy its valency by forming one, two, three, or four bonds at a time with another element including carbon itself.

For example, C₂H₆, C₂H₄, HCN et cetera.

Carbon has a unique property of catenation that is, it can form long chains of interconnected carbon atoms.
