LIFE SCIENCE

Detailed explanation-1: -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-2: -Organic compounds are generally any chemical compounds that contain carbon-hydrogen bonds. All the options are true about Organic compounds except option I, Organic compounds does not contain calcium. They are molecules that contain carbon atoms covalently bonded to hydrogen atoms (C-H bonds).

Detailed explanation-3: -Organic compounds have strong covalent compounds which make them relatively unreactive.

Detailed explanation-4: -One or more carbon atoms are present in all the organic compound. Thus, the statement is true.

Detailed explanation-5: -Amines are organic compounds which contain and are often actually based on one or more atoms of nitrogen. Structurally amines resemble ammonia in that the nitrogen can bond up to three hydrogens, but amines also have additional properties based on their carbon connectivity.
