Concept introduction:
To state:
Which aldehyde or ketone gives in an aldol reaction the compound represented by the model.
Answer to Problem 23VC
The ketone that gives in an aldol reaction the compound represented by the model is 3-pentanone.
Explanation of Solution
The compound represented by the model is
An analysis of the structure indicates it can be produced by the aldol reaction between two 3-pentanone molecules and dehydrating the aldol obtained.
The ketone that gives in an aldol reaction the compound represented by the model is 3-pentanone.
b)
Interpretation:
Which aldehyde or ketone gives in an aldol reaction the compound represented by the model is to be stated.
Concept introduction:
Aldehydes with α-hydrogen undergo a base catalyzed carbonyl condensation reaction in aldol condensation. In this reaction two molecules of the reactant combine by forming a bond between α- carbon of one molecule and the carbonyl carbon of the second molecule. The product obtained is a β-hydroxyaldehyde.
To state:
Which aldehyde or ketone gives in an aldol reaction the compound represented by the model.
Answer to Problem 23VC
The aldehyde that gives in an aldol reaction the compound represented by the model is 3-methylbutanal.
Explanation of Solution
The compound represented by the model is
An analysis of the structure indicates it can be produced by the aldol reaction between two 3-methylbutanal molecules and dehydrating the aldol obtained.
The aldehyde that gives in an aldol reaction, the compound represented by the model is 3-methylbutanal.

- Please explain how to calculate the pH.arrow_forwardI'm having trouble with converting lewis diagrams into VSEPR diagrams. I currently have this example of C2BrCl3 which I want to turn into a lewis structure, but I'm not sure what steps I need to do in order to do so. I have the table written down, however, there's two central atoms so what would I do? There seems to be 4 electron domains on the carbon atom and no lone pairs so it would seem like this shape would be tetrahedral. Here's what I have now.
