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.
