Given the following experimental scenario, indicate which physical constants are relevant. Maleic anhydride (200 mg) is dissolved in 10 mL of diethyl ether. Diethyl amine (2 equivalents) is dissolved in 2 mL of diethyl ether and slowly added to the maleic anhydride solution while cooling the reaction mixture in an ice bath. Q 3 options: Diethyl ether melting point (-116 oC) Diethyl ether boiling point (35 oC) maleic anhydride boiling point (202 oC) Diethyl amine boiling point (55 oC) Diethyl amine density (1.0475 g/mL) Diethyl amine MW 73 Diethyl ether density (0.714 g/mL) Hint: Consider at which temperature the reaction is run. Which of the boiling points and melting points might come into play? Also consider which constants you need to calculate the amounts to be used.
