Problem- You work in a small-scale manufacturing facility that uses acetophenone as the starting material for a multi-step synthesis. Your company buys ~98% pure acetophenone from a major manufacturer and purifies it in-house prior to its use in the multi-step synthesis. You are given the job to purify 100g of impure acetophenone.
Explain your strategy for completing your purification task, defining your rationale as relevant.
