Afisher esterification is performed with methanol and benzoic acid. all the oxygen atoms of the methanol are isotopically labelled oxygen-18 atoms, and none of the oxygen atoms of the benzoic acid are oxygen-18, i. e. in the benzoic acid all the oxygens are oxygen-16. which of the following products would you expect from this reaction? (a) phenyl acetate, with the ether oxygen being oxygen-18.(b) methyl benzoate, with both oxygens being oxygen-18.(c) phenyl acetate, with both oxygens being oxygen-18.(d) methyl benzoate, with both oxygens being oxygen-16.(e) phenyl acetate, with both oxygens being oxygen-16.(f) phenyl acetate, with the carbonyl oxygen being oxygen-18.(g) methyl benzoate, with the carbonyl oxygen being oxygen-18.(h) methyl benzoate, with the ether oxygen being oxygen-18.
