Which products in problem 20 .28 will produce methyl cyclohexylmethanoate when treated with NaOCH 3 is to be identified. Concept introduction: The reaction in which one form of an ester is converted to another form by changing the carbon skeleton of the (OR) part of the ester is called transesterification. The transesterification reaction is a nucleophilic addition-elimination reaction. In the first step, the nucleophile adds the electro-poor carbonyl carbon of an ester, which forces the bonding pair of carbonyl p bond onto the O atom. A negative charge is produced on that O, and a tetrahedral intermediate is formed. In the second step, the tetrahedral intermediate undergoes nucleophilic elimination to form the transesterification product. Transesterification is a reversible reaction.

Question

Predict the major products of this reaction: excess H+ NaOH ? A Note that the first reactant is used in excess, that is, there is much more of the first reactant than the second. If there won't be any products, just check the box under the drawing area instead. Explanation Check Click and drag to start drawing a structure. © 2025 McGraw Hill LLC. All Rights Reserved.
