How many moles of carbon dioxide are generated when one mole of the compound shown is treated with warm, concentrated KMnO₄?

A) 1
B) 2
C) 3
D) 4
E) 8

The balanced chemical equation for the reaction shows that one mole of the compound reacts with 3 moles of KMnO4 to produce 2 moles of CO2. Therefore, when one mole of the compound reacts, 2/3 moles of KMnO4 are consumed, leading to the production of 2/3 moles of CO2. However, since the question asks for the number of moles of CO2 generated, we can round up to the nearest whole number, which is 1.5. This means that when one mole of the compound is treated with KMnO4, approximately 1.5 moles of CO2 are generated. Rounded to the nearest whole number, the answer is 2, which is choice C.
