Chapter 1 Introduction and Review

1) In the midst of a late-night study session of organic chemistry, a discovery was made while catching the final 5 minutes of an infomercial on television. The spokesperson boasted about the superiority of their line of car tires compared to others on the market due to their use of solely natural rubber sourced from the resin of rubber trees. How could a scientist verify her claims that no fossil fuel-based products were involved in the production of her tire brand?

Answer: Compounds created from fossil fuel-derived products exhibit a lower 14C content. Conversely, plant-derived compounds are recently synthesized from atmospheric CO2 and feature a higher 14C content.
