Aldehydes have properties that are diverse and that depend on the remainder of the molecule. Smaller aldehydes such as formaldehyde and acetaldehyde are soluble in water, and the volatile aldehydes have pungent odors. Aldehydes can be identified by spectroscopic methods. Using IR spectroscopy, they display a strong ν CO band near 1700 cm −1.
A ketone compound containing a carbonyl group (C=O) For organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom.
Acetaldehyde (IUPAC systematic name ethanal) is an organic chemical compound with the formula CH 3 CH=O, sometimes abbreviated as MeCH=O.It is a colorless liquid or gas, boiling near room temperature.
This unsaturated aldehyde is then partially hydrogenated to form 2-ethylhexanal, a precursor to plasticizers such as bis(2-ethylhexyl) phthalate. [ 4 ] Butyraldehyde is a component in the two-step synthesis of trimethylolpropane , which is used for the production of alkyd resins .
Glutaraldehyde is an organic compound with the formula (CH 2) 3 (CHO) 2.The molecule consists of a five carbon chain doubly terminated with formyl (CHO) groups. It is usually used as a solution in water, and such solutions exists as a collection of hydrates, cyclic derivatives, and condensation products, several of which interconvert.
Reducing form of glucose (the aldehyde group is on the far right). A reducing sugar is any sugar that is capable of acting as a reducing agent. [1] In an alkaline solution, a reducing sugar forms some aldehyde or ketone, which allows it to act as a reducing agent, for example in Benedict's reagent.

General structure of 1,2-, 1,3-, and 1,4-dicarbonyls. In organic chemistry, a dicarbonyl is a molecule containing two carbonyl (C=O) groups.Although this term could refer to any organic compound containing two carbonyl groups, it is used more specifically to describe molecules in which both carbonyls are in close enough proximity that their reactivity is changed, such as 1,2-, 1,3-, and 1,4 ...
