Sancho's Organic Chemistry Lesson Notes For Ordinary Level

OBJECTIVES OF THE TOPIC:

The compounds obtained from minerals, that is, non – living sources are known as in – organic

compounds. The compounds derived from animal and vegetable sources have almost similar

composition of elements. Nearly, all of them were composed of carbon, hydrogen, and oxygen

elements. In view of the similarity of composition, the compounds obtained from living

organism that is, animals, and plants, were collectively called organic compounds.

For example, table salt, marble and carbon dioxide were inorganic, whereas acetic acid (from

vinegar), alcohol (from wine), tartaric acid (from grapes), citric acid (from lemon), and sucrose

(from sugarcane) were organic.
