Question

What statement is TRUE about the mechanism for the reaction shown here? CH(CH2)2CO CH -COẠCH NaOH CH3(CH)1200CH excess heat CH(CH3COACH 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.
