Chapter 21.SE, Problem 75AP

One frequently used method for preparing methyl esters is by reaction of carboxylic acids with diazomethane, CH2N2.

Chapter 21.SE, Problem 75AP, One frequently used method for preparing methyl esters is by reaction of carboxylic acids with

The reaction occurs in two steps: (l) protonation of diazomethane by the carboxylic acid to yield methyldiazonium ion, CH3N2+, plus a carboxylate ion; and (2) reaction of the carboxylate ion with CH3N2+.

(a) Draw two resonance structures of diazomethane, and account for step 1.

(b) What kind of reaction occurs in step 2?
