Enol tautomer of 2,4-pentanedione has to be drawn. Concept Introduction: Tautomerism is the ability of a molecule to exist in more than one chemical form. Tautomers are formed by the migration of a hydrogen atom, accompanied by the switching of a single and neighboring double bond. The only difference in keto-enol tautomers is the location of hydrogen and double bond.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone

Which ketone in each pair is more reactive? a. 2-heptanone or 4-heptanone b. bromomethyl phenyl ketone or chloromethyl phenyl ketone

What is the major difference between the base-catalyzed and acid-catalyzed processes for nucleophilic addition of water to aldehydes and ketones? a. The base-catalyzed reaction takes place rapidly because hydroxide ion is a much better nucleophile than neutral water. b. The rate of reaction in base catalyzed process is slower than acid catalyzed process. c. The acid-catalyzed reaction takes place rapidly because the protonated carbonyl compound is a much better electrophile than the neutral compound. d. Only 1 and 3 are correct.
