GENERAL KNOWLEDGE

Detailed explanation-1: -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.

Detailed explanation-2: -Although all organic compounds contain carbon, and almost all have hydrogen, most of them contain other elements as well. The most common other elements in organic compounds are oxygen, nitrogen, sulfur, and the halogens.

Detailed explanation-3: -The reason lies within the uniqueness of carbon’s structure and bonding capabilities. Carbon has four valence electrons, and therefore makes four separate covalent bonds in compounds. Carbon has the ability to bond to itself repeatedly, making long chains of carbon atoms, as well as ringed structures.
