Quiz | Enols – Enolates, and the Aldol Condensation – Part 2
The acid catalyzed reaction of Br2 with propanone will lead to which of the following products?
Bromomethane and acetic acid
Which organometallic reagent results in a 1,4-addition?
All of the above
Which statement is incorrect about an enolate ion?
An enolate can be formed by a base such as NaOH
An enolate is a good electrophile
An enolate plays a role in the Michael addition
An enolate is the conjugate base of an enol
What are the different steps of a Robinson annulation?
1,2-Addition, Intramolecular aldol condensation
Enolization, Aldol dehydration
Michael addition, Intermolecular aldol condensation
Michael addition, Intramolecular aldol condensation, Aldol dehydration
What are the two chemical functions of a Michael addition product?
One carbonyl and one alcohol
One carbonyl and one alkene
Which statement is correct about the Grignard reagent and α,β-Unsaturated Carbonyls?
The reaction is selective (1,2- OR 1,4-addition) but depends on reagent and substrate structure
The reaction is not selective: we have products from a 1,2-addition AND from 1,4-addition
The reaction is really slow compared to RLi and R2CuLi
The reaction is selective and leads to the formation of the product from a 1,2-addition
