Question
Chapter 16, Problem 16.68P
Interpretation Introduction
Interpretation: The reason as to why ferulic acid, a natural product found in rice, oats and other plants, is both an antioxidant and a sunscreen is to be explained.
Concept introduction: Conjugated diene consists of two double bonds that are separated by a single bond, whereas isolated diene also consists of two double bond but they are separated by two or more carbon atoms.
The energy difference between the ground and excited state decreases when number of conjugated bonds increases. Due to this absorption shifts to the longer wavelengths.

An open vessel containing water stands in a laboratory measuring 5.0 m x 5.0 m x 3.0 m at 25 °C ; the vapor pressure (vp) of water at this temperature is 3.2 kPa. When the system has come to equilibrium, what mass of water will be found in the air if there is no ventilation? Repeat the calculation for open vessels containing benzene (vp = 13.1 kPa) and mercury (vp = 0.23 Pa)
Every chemist knows to ‘add acid to water with constant stirring’ when diluting a concentrated acid in order to keep the solution from spewing boiling acid all over the place. Explain how this one fact is enough to prove that strong acids and water do not form ideal solutions.
