What product will be formed on reaction of propanal with 2-methylpropanal in the presence of NaOH? What products will be formed? Write the name of the reaction also.

When propanal react with 2-methylpropanal in the presence of NaOH, the mixture of aldehydes are formed.

Both the reactants have an alpha-hydrogen and hence, can undergo cross aldol reaction in the presence of NaOH.

The products formed in this reaction are

This is called cross aldol reaction.
