CH,(CH2)2CO,CH CH3(CH)12CO,CH „Coch! NaOH excess heat CH3(CH)2CO,CH, Water attacks the carbonyl carbon to form a tetrahedral intermediate. The first step of the reaction involves protonation of the ester carbonyl oxygen. One of the products formed is glycerol. The hydroxide deprotonates the alpha carbon.
