Carbon Compounds

INTRODUCTION




In constituent(a) chemistry , there exist a divalent chemical unit consisting of a carbon (C) and an group O (O) atom which is connected by a double tie up , called carbonylic compounds . The carbonyl compou nds are of utmost importance to the organic chemistry. They are consti tuents of fabrics, flavouring, plastics and drugs. This group is a constitu ent of carboxylic acids , esters, anhydrides , acyl halides , amides and quinines and is the character functional group or the reactive group of aldehydes and ketones.

STRUCTURE

The carbonyl carbon atom is sp2hybridized and forms three sigma (?) draws. The fourth valence negatron of the carbon remains in its p- orbital and forms a ? - bond with oxygen by overlap with p - orbital of oxygen. In addition the oxygen atom also has two non adhere electron pairs. Thus the carbonyl carbon and the free atoms given over to it lie in the same plane and the ? -electron cloud is higher up and below this plane. The bond angles are approximately 120? as it is...If you want to get a full essay, order it on our website: Orderessay
