Solution
Cocaine $\left(\mathrm{C}_{17}, \mathrm{H}_{21}, \mathrm{NO}_4\right)$ is natural alkaloid obtained from leaves of coca. (Erythroxylon coca). It is powerful CNS stimulant which induce a sense of well being, pleasure and delays fatigue.
Morphine $\left(\mathrm{C}_{17} \mathrm{H}_{19} \mathrm{O}_3 \mathrm{~N}\right)$ is extracted from Papaver somniferum and relieve pain.
Heroin $\left[\mathrm{C}_{17} \mathrm{H}_{17}\left(\mathrm{OC}_2 \mathrm{H}_3 \mathrm{O}\right)_2 \mathrm{ON}\right]$ is semi-synthetic opiate. It is about three times more potent than morphine.
