What is aldehyde?
An aldehyde is an organic chemical that contains a functional group with the formula RCH=O. The functional group (without the "R" side chain) is an aldehyde, however it can also be categorized as a formyl group. Aldehydes are widely used and serve vital roles in industry and biology.
Aldehydes have a carbon center that is linked to oxygen by a double bond, hydrogen by a single bond, and a third substituent, which is carbon or, in the case of formaldehyde, hydrogen by a single bond. The middle carbon is frequently described as sp2-hybridized. The aldehyde group is polar in several ways. The length of the C=O bond is around 120-122 picometers.
