Concept explainers
Interpretation:
The amide that is an important hormone in human body has to be chosen from the given options.
Concept Introduction:
Organic compounds are the important basis of life. They include gasoline, coal, dyes, and clothing fibers etc. The compounds that are obtained from living organisms are termed as organic compounds and those obtained from the earth are known as inorganic compounds. Organic compounds are found in earth also apart from living organisms. All the organic compounds contain the element carbon. Urea was synthesized in the laboratory which is an organic compound.
Organic compounds contain heteroatom also. Some of them are nitrogen, sulfur, oxygen etc. Nitrogen containing organic compounds is of two important types and they are
