What are Organic Compounds? ChemTalk

Vitalism was a widespread conception that substances found in organic nature are formed from the chemical elements by the action of a "vital force" or "life-force" (vis vitalis) that only living organisms possess. In the 1810s, Jöns Jacob Berzelius argued that a regulative force must exist within living bodies. Berzelius also contended that compounds could be distin… Witryna3 sie 2024 · Covalent compounds that contain predominantly carbon and hydrogen are called organic compounds A covalent compound that contains predominantly carbon and hydrogen..One convention for representing the formulas of organic compounds is to write carbon first, followed by hydrogen and then any other elements in alphabetical … quotes about a new year and new beginning
