Question

At the start of the reaction in Experiment 8, triethylene glycol is mixed with two other chemicals and heated until it becomes a uniform liquid. What is actually occurring? Choose all of the correct terms from among the following: "melting", "boiling", "dissolving", "emulsifying", "deprotonating", "neutralizing".

1. Place 0.5 g of 1,3-diphenylacetone, 0.5 g of benzil, and 5 mL of triethylene glycol in a 25 mL Erlenmeyer flask.

2. Add a magnetic stir bar and place the flask on a hotplate.

3. Set the temperature control to about “3” and stir the mixture until a homogenous solution is obtained.

**The goal is not to boil here—the boiling point of triethylene glycol is over 280 °C!—nor to accelerate the reaction—the base that causes the reaction to begin is not even present yet. Rather, we just want the starting solid materials completely mixed into a liquid so the reaction can run well once the base solution is added.

Explanation / Answer

1) 1,3-Diphenyl acetone, benzil and triethylene glycol when mixed the phenomenon is deprotonation

2)When magnetic stirr is added and placed on hot plate then the phenomenon is emulsifying

3)When the temperature controlled & stirred until the homogeneous solution is obtained. the the phenomenon called dissolving
