1. Draw the aldol product formed from an aldol/Claisen reaction with the given starting material(s) using OH or RO in H20 or ROH. (Hint: the product of an aldol reaction is a B-hydroxy carbonyl compound or an a,b- unsaturated carbonyl compound. The a,ß-unsaturated carbonyl will be the major product unless elimination of H2O cannot form the conjugated system.) он Но, но Н,0 НО. ОН НО. он H, H НО. НО.
