WebAnswer (1 of 5): Aldol Condensation plays a vital role in the organic synthesis, creating a path to form carbon-carbon bonds. “Aldol Condensation can be defined as an organic reaction in which enolate ion reacts with a carbonyl compound to form β-hydroxyketone or β-hydroxyaldehyde, followed by a ... WebThe aldol condensation reaction occurs for aldehdyes or ketones with an enolizable proton. An enolizable proton is a proton attached the carbon next to the carbonyl. The carbon in this position is called an (alpha) carbon. The first step in an aldol condensation is deprotonation at the position of the aldehyde or ketone. An example is show below.
