Here, in all the reactions, base is given and one carbonyl
compound is also given. So 1st base forms enolate ion by taking
alpha proton of carbonyl. Then this enolate attacks on the another
molecule of same compounds carbonyl grp.. To form bita hydroxy
carbonyl compound.. On condensation H2O removed and enone will be
formed.
