Question 1

The empirical formula of styrene is CH; its molar mass is 104.1 g/mol. What is the molecular formula of styrene?

◦ C₂H₄

◦ C₈H₈

◦ C₁₀H₁₂

◦ C₆H₆

◦ None of these are correct.

Question 2

The following equation describes the oxidation of ethanol to acetic acid by potassium permanganate:

5.00 g of ethanol and an excess of aqueous KMnO₄ are reacted, and 5.99 g of HC₂H₃O₂ result. What is the percent yield?

◦ 100%
◦ 91.9%
◦ 30.6%
◦ 8.1%
◦ 5.99 g HC₂H₃O₂ is impossible since it represents more than 100% yield.
