Organic chemistry Organic chemistry is one of the ‘branches’ of chemistry and is seen as distinct from other branches‚ such as inorganic and physical chemistry. It can be described as the chemistry living processes (often referred to as biochemistry) but extends beyond that. It focuses almost entirely on the chemistry of covalently bonded carbon molecules and as well as life processes‚ it includes the chemistry of other types of compounds‚ including plastics‚ petrochemicals‚ drugs and paint
