Devise a simple synthetic route to an amide from a carboxylic acid. Give a mechanism for the final step and explain why the reagents are not added 1:1 in the final step

1st step: SOCl 2 or PCl 3 to form an acyl chloride, which is now significanlty more electrophilic based on leaving gorup abiliity, hence an amine can now attack the acyl chloride to form the amide, where as ...
