An organic compound always contains carbon. A few exceptions are carbon monoxide, carbon dioxide, carbonates, cyanides, cyanates, carbides, and thyocyanates, which are considered inorganic. Examples of organic compounds are carbohydrates, lipids, proteins and nucleic acids.
Even though organic compounds only contain a few. elements (mainly C, H, O, N, S, and P), the unique. ways carbon atoms can attach together to form. molecules leads to millions of different organic. compounds. Life as we know it is because of organic chemistry. Organic chemistry is a branch of chemistry that. focuses on compounds that contain carbon. â¢ Carbon can bond to as. many as four other atoms. Bonds to carbon are very. strong and nonreactive. â¢.
