Organic compounds containing Nitrogen MCQs

Organic chemistry is the branch of chemistry focused on studying carbon-containing compounds, including those with hydrogen and their derivatives. Currently, around five million organic compounds are known. These compounds primarily consist of carbon and hydrogen. Thus, organic chemistry is defined as the study of hydrocarbons and their derivatives. Essentially, it is the chemistry of carbon, where carbon compounds are categorized based on the arrangement of carbon atoms and the attached groups of atoms.
