Web14 jan. 2024 · In chemistry, the carboxyl group is an organic, functional group consisting of a carbon atom that's double-bonded to an oxygen atom and singly bonded to a hydroxyl group. Another way to view it is as a carbonyl group (C=O) that has a hydroxyl group (O-H) attached to the carbon atom. The carboxyl group is sometimes referred to as the carboxy ...

Did you know?
Carbonyl iron is a highly pure (97.5% for grade S, 99.5+% for grade R) iron, prepared by chemical decomposition of purified iron pentacarbonyl. It usually has the appearance of grey powder, composed of spherical microparticles. Most of the impurities are carbon, oxygen, and nitrogen. BASF invented carbonyl iron powder in 1925 and claims to be the world's leading producer. In 1934, BASF was also involved in the development of the very first magnetic tapes used by the … Web6 okt. 2024 · Cram's rule, proposed by Donald Cram in 1952, [1] was the earliest model proposed for rationalising the stereoselectivity of nucleophilic additions to carbonyl groups with α-stereocentres. The model involved assigning each α-substituent a relative "size" (small, medium, and large), then placing the carbonyl oxygen antiperiplanar to the largest …
