a)
Interpretation:
The products of the reaction shown are to be given.
Concept introduction:
Compounds having two carboxyl groups attached to a carbon readily undergo decarboxylation, when heated, to yield monocarboxylic acids.
To give:
The products of the reaction shown.
b)
Interpretation:
The product of the reaction shown is to be given.
Concept introduction:
In the first reaction the base abstracts a proton to yield an enolate ion. In the second reaction alkylation takes place.
To give:
The product of the reaction shown.
c)
Interpretation:
The products of the reaction shown are to be given.
Concept introduction:
When carboxylic acids are treated with Br2 and PBr3, bromination occurs at the carbon α- to the carboxyl group and the acid group also is converted into an acyl bromide. When treated with water the acyl bromide gets hydrolyzed to yield the free acid.
To give:
The products of the reaction shown.
d)
Interpretation:
The products of the reaction shown are to be given.
Concept introduction:
Methyl
To give:
The products of the reaction shown.
