CyHN ch is worth 10 por intermediate #2 from intermediate #1 and for intermediate #3 going to the final product. A. Show the key species in the DCC amine-carboxylic acid coupling. Use proper reaction arrows to form amine OH + N-Cy Intermediate #1 - an adduct from DCC and the carboxylic acid (anhydride-like) - no involvement of he amine yet NHCy -NH₂ (DCC) Cy = cyclohexyl Intermediate #3 - from an internal transfer of protons in #2 that sets up the formation of the amide and the urea byproduct Intermediate #2 - the tetrab intermediate like in any n acyl substitution - add ar and do nothing else

Please help

Please provide a balanced equation for the reaction using structural formulas.

1. what precautions should one use when working with phenacetin 2. Calculate the theoretical yield in grams for the Williamson ether synthesis of phenacetin. Repeat the calculation for the amide synthesis of phenacetin. (The density of p-phenetidine is 1.065 g/mL.)
