Question:
Helicenes are extended fused polyaromatic hydrocarbons that have a helical or screw-shaped structure.
a. A 0.1450-g sample of solid helicene is combusted in air to give 0.5063 g CO2. What is the empirical formula of this helicene?
b. If a 0.0938-g sample of this helicene is dissolved in 12.5 g of solvent to give a 0.0175 M solution, what is the molecular formula of this helicene?
c. What is the balanced reaction for the combustion of this helicene?
