Detailed explanation-1: -Almost all the bonds involved in organic compounds are covalent bonds. Covalent bonds can be non-polar or polar. For covalent bonds formed between two identical atoms, the electron pairs are shared equally between the two nuclei.

Detailed explanation-2: -Organic molecules are molecules that are made of carbon and hydrogen, and can include other elements. Organic molecules must contain carbon atoms covalently bonded to hydrogen atoms (C-H bonds). They usually involve oxygen and can also contain nitrogen, sulfur, phosphorous, and others.

Detailed explanation-3: -Compounds that consist primarily of elements other than carbon and hydrogen are called inorganic compounds; they include both covalent and ionic compounds.

Detailed explanation-4: -Organic compounds and functional groupsEdit The chemistry of carbon is almost entirely due to covalent bonding. Almost without limit, carbon can form four covalent bonds with a wide range of non-metallic elements. Carbon is able to form long chains of atoms to form quite stable molecules.
