Q.30. - Organic Chemistry

Question

Question: Draw the product formed from an aldol reaction with the given starting material(s) using $\mathit{O}\mathit{H}\mathbf{,}\mathbf{ }{\mathit{H}}_{\mathbf{2}}\mathit{O}$ .

Step-by-Step Solution

Answer

Answer

Step 1: Aldol reaction

Aldol reactions are important as they help in adding a C-C bond between the two reactants. This reaction can take place either in between two same reactants or two different reactants. 

Step 2: Cross-aldol reaction

The products of the cross-aldol reaction are a mixture of two or more substances. However, this reaction can only be useful when one of the two reactants does not have an  $\mathit{\alpha }$-hydrogen and fewer products rather than four are obtained.

Step 3: Products of the given reactions

a. The first reaction is the simple aldol reaction. The given reactant forms a C-C bond with another structure of its own. The product is shown hereunder.

b. The reaction is cross-aldol between two different carbonyl compounds. The product of the reaction is shown hereunder.

c. The reaction is cross-aldol between two different carbonyl compounds. The product of the reaction is shown hereunder.
