Detailed explanation-2: -Four elements, hydrogen, carbon, oxygen and nitrogen, are the major components of most organic compounds. Consequently, our understanding of organic chemistry must have, as a foundation, an appreciation of the electronic structure and properties of these elements.

Detailed explanation-3: -Carbon is the main element in organic compounds. Carbon can form stable bonds with many elements, including itself. There are four major types of organic compounds: carbohydrates, lipids, proteins, and nu cleic acid s.
