Answer 1

Caffeine (1,3,7-Trimethylpurine-2,6-dione) is a methylxanthine alkaloid used as a stimulant for central nervous system. It was first discovered in 1820 in cacoa plant.^ref At that time it was employed as drug for analgesic.^ref It is one of the natural product that does not exist in the liquid state, but it sublimes! It is noteworthy to mention that, it is a white crystalline solid with bitter taste.^ref It is soluble in water and thus found as aqueous solutions.^ref There are beverages, such as coffee, tea, colas, etc. which contains caffeine. A recommended dose of caffeine, i.e. around 300 mg per day can increase alertness without any side effect. Overdose results in a condition termed as caffeinism; its a combination of several unpleasant symptoms like restlessness, insomnia, headaches, etc.^ref In the present experiment we are going to isolate caffeine from No-Doz tablets via recrystallization.

Be sure to refer where ever it is required. I am not putting any reference. If reference are not included, it will consider as plagarism.
