Concept Introduction:
Organic compounds are the compounds that are mainly composed of C and H atoms. The branch of chemistry that deals with the preparation, reactions, and properties of organic compounds. The molecular formula of an organic compound represents the number of bonded atoms with their atomic symbols. The structural formula represents all the bonded atoms with

- Alkaloids are basic nitrogen-containing compounds of plant origin, many of which are physiologically active when administered to humans. Ingestion of coniine, isolated from water hemlock, can cause weakness, labored respiration, paralysis, and eventually death. Coniine is the toxic substance in the “poison hemlock” used in the death of Socrates. In small doses, nicotine is an addictive stimulant. In larger doses, it causes depression, nausea, and vomiting. In still larger doses, it is a deadly poison. Solutions of nicotine in water are used as insecticides. Cocaine is a central nervous system stimulant obtained from the leaves of the coca plant.Classify each amino group in these alkaloids according to type (primary, secondary, tertiary, aliphatic, aromatic, heterocyclic).arrow_forward17.
