3-Methyl-2-butanone, naming

Ketones may also be named using functional class lUPAC nomenclature by citing the two groups attached to the carbonyl m alphabetical order followed by the word ketone Thus 3 methyl 2 butanone (substitutive) becomes isopropyl methyl ketone (functional class)...

The results indicate that the product ratio is determined by the competition between the various reaction steps. Under base-catalyzed conditions, 2-butanone reacts with benzaldehyde at the methyl group to give l-phenylpent-l-en-3-one. Under acid-catalyzed conditions, the product is the result of condensation at the methylene group, namely, 3-methyl-4-phenylbut-3-en-2-one. Under the reaction conditions used, it is not possible to isolate the intermediate ketols, because the addition step is rate-limiting. These intermediates can be... 

Pinacol rearrangement is a dehydration of a 1,2-diol to form a ketone. 2,3-drmethyl-2,3-butanediol has the common name pinacol (a symmetrical diol). When it is treated with strong acid, e.g. H2SO4, it gives 3,3-dimethyl-2-butanone (methyl r-butyl ketone), also commonly known as pinacolone. The product results from the loss of water and molecular rearrangement. In the rearrangement of pinacol equivalent carbocations are formed no matter which hydroxyl group is protonated and leaves.

Most common names for ketones are formed by naming both alkyi groups on the carbonyl carbon, arranging them alphabetically, and adding the word ketone. Using this method, the common name for 2-butanone becomes ethyl methyl ketone. 

Named systematically by replacing the ending -e by -one, but many common names exist such as acetone or dimethyl ketone for propanone, and methyl ethyl ketone for butanone... 

Synonyms/Trade Names 2-Butanone peroxide, Ethyl methyl ketone peroxide, MEKP, MEK peroxide. Methyl ethyl ketone hydroperoxide ...

Aldehydes and ketones can be named in a systematic way by counting the number of carbon atoms (including the carbonyl carbon) that they contain. The name of the aldehyde or ketone is based on the hydrocarbon with the same number of carbon atoms. The ending -al for aldehyde or -oiie for ketone is added as appropriate. Draw the structural formulas for the following aldehydes or ketones (a) propanal, (b) 2-pentanone, (c) 3-methyl-2-butanone, (d) 2-methylbutanaL... 

Two of the most widely used ketones are commonly known by non-IUPAC names Propanone is called acetone, and butanone is known as methyl ethyl ketone, or MEK,... 

Freund was able to synthesize what was named acetyl-methyl (propanone), acetyl-ethyl (butanone), propionyl-ethyl (3-pentanone) and benzyl-ethyl (1 -phenylpropanone). 

Ketones react with diols in a manner identical with aldehydes. An example reacts 2-butanone (16) with 1,3-propanediol (63) to form cyclic ketal 64. The cyclic ketal in this case is a six-membered ring containing two oxygen atoms, and it is known as a 1,3-dioxane. The name of 64 is 2-ethyl-2-methyl-l,3-dioxane. 

A Methyl ethyl ketone (MEK) is a common industrial solvent. Its lUPAC name is butanone. Write its Lewis formula and show how its common name, MEK, is derived.
