Acetone is a weak Lewis base that forms adducts with soft acids like I 2 and hard acids like phenol. Acetone also forms complexes with divalent metals. [48] [49] Under ultraviolet light, acetone fluoresces.. [50] The flame temperature of pure acetone is 1980 °C. [51]

Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
Acetone and acetic anhydride ((CH 3 C(O)) 2 O) upon the addition of boron trifluoride (BF 3) catalyst: [11] (CH 3 C(O)) 2 O + CH 3 C(O)CH 3 → CH 3 C(O)CH 2 C(O)CH 3 A second synthesis involves the base-catalyzed condensation (e.g., by sodium ethoxide CH 3 CH 2 O − Na + ) of acetone and ethyl acetate , followed by acidification of the sodium ...
The most common Lewis bases are anions. The strength of Lewis basicity correlates with the pK a of the parent acid: acids with high pK a 's give good Lewis bases. As usual, a weaker acid has a stronger conjugate base. Examples of Lewis bases based on the general definition of electron pair donor include: simple anions, such as H − and F −
In organic chemistry, a ketone / ˈ k iː t oʊ n / is an organic compound with the structure R−C(=O)−R', where R and R' can be a variety of carbon-containing substituents. Ketones contain a carbonyl group −C(=O)− (a carbon-oxygen double bond C=O). The simplest ketone is acetone (where R and R' is methyl), with the formula (CH 3) 2 CO ...

Acetyl chloride was first prepared in 1852 by French chemist Charles Gerhardt by treating potassium acetate with phosphoryl chloride. [4]Acetyl chloride is produced in the laboratory by the reaction of acetic acid with chlorodehydrating agents such as phosphorus trichloride (PCl 3), phosphorus pentachloride (PCl 5), sulfuryl chloride (SO 2 Cl 2), phosgene, or thionyl chloride (SOCl 2).
