Detailed explanation-1: -All organic compounds contain carbon, as well as hydrogen unless it has been replaced by another element.

Detailed explanation-2: -This means that all organic compounds have in common the presence of carbon atoms and hydrogen atoms. In addition, different organic compounds may contain oxygen, nitrogen, phosphorous, and other elements.

Detailed explanation-3: -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-4: -Carbon is the basis of organic chemistry and its compounds. It has the ability to catenate and form various organic compounds.

Detailed explanation-5: -How many carbon-containing molecules are there? The current estimate is around 20 million different known organic compounds.
