Question

In this lab you are doing a condensation reaction between two aromatic aldehydes. Will this type of reaction occur with any two aldehydes or only aromatic aldehydes?

A.This reaction will only occur with aromatic aldehydes; the aromatic ring is required for resonance stabilization of intermediates in the reaction mechanism.

B.This reaction will only occur with aromatic aldehydes, the aromatic ring coordinates to the catalyst making the reaction more favorable.

C. This reaction can occur with any aldehydes, any aldehyde can coordinate to the catalyst and result in this condensation reaction.

D.This reaction will only occur with aromatic aldehydes, the aromatic ring destabilizes the starting material making it more reactive.

E. This reaction can occur with any aldehydes, non-aromatic aldehydes are smaller, and thus undergo this condensation reaction even faster.

Explanation / Answer

C. This reaction can occur with any aldehydes, any aldehyde can coordinate to the catalyst and result in this condensation reaction.

(The only requirement is that aldehyde should have alpha hydrogen for enolization followed by condensation)
