Why doesn’t the reaction between 3-mercaptopropionic acid and methyl iodide yield a methyl ester? [closed]
Problem
Answer
Question
I don’t understand why 3‐methylthiopropionic acid (X) is the correct answer. Wouldn’t sulfur and carbon have similar electronegativities?
As the consequence, isn’t it more ...
