Brief Explanations:
A compound is a substance made up of two or more different types of elements chemically combined. $NaHCO_3$ (sodium bicarbonate) is composed of sodium (Na), hydrogen (H), carbon (C), and oxygen (O). $C_8H_{18}$ (octane) is composed of carbon (C) and hydrogen (H). $O_3$ (ozone) and $Cl_2$ (chlorine) are made of only one - type of element, so they are not compounds.
