Which of the following represents a compound? c20 h2o o2 h2

Option (b) is the correct answer.

Explanation:

A compound is defined as a substance that has two or more number of different atoms which are chemically combined to each other in a fixed ratio by mass.

For example, contains two atoms of hydrogen and one atom of oxygen which are chemically combined together in 2:1 ratio. Therefore, it is a compound.

On the other hand, if a substance contains only atoms of one type of element then it is known as a molecule.

For example, , , and are all molecules.

Thus, we can conclude that out of the given options represents a compound.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

where are the choice options?
