Organic compounds containing Nitrogen MCQs

Organic chemistry is that branch of chemistry which deals with the study of compounds of carbon with hydrogen and their derivatives. Presently about five million organic compounds are known. Organic compounds were found to contain mainly hydrogen and carbon. Therefore, organic chemistry is defined as the study of hydrocarbons and their derivatives. Organic chemistry is essentially the chemistry of carbon. Carbon compounds are arranged according to how the carbon atoms are arranged and what other groups of atoms are attached.
