One of the most bizarre reactions in chemistry is called the Ugi reaction:
R₁C(=O)R₂ + R₃ - NH₂ + R₄COOH + R₅NC →
R₄C(=O)N(R₃)C(R₁R₂)C=ONHR₅ + H₂O

(a) Write out the balanced chemical equation for the Ugi reaction, for the case where R = CH₃CH₂CH₂CH₂CH₂CH₂— (this is called the hexyl group) for all compounds. 

(b) What mass of the “hexyl Ugi product” would you form if 435.0 mg of CH₃ CH₂CH₂CH₂CH₂CH₂NH₂ was the limiting reactant?
