In this reaction I spelled out the trick to write the merchandise of knoevenagel Response & Reformatsky response with element system. A Knoevenagel condensation is actually a nucleophilic addition of the Lively hydrogen compound to a carbonyl group followed by a dehydration reaction in which a molecule of water is eradicated (hence condensation). The item is usually an α,β-unsaturated ketone (a conjugated enone).
