The vapor pressure of the pure solvent and the vapor pressure of its solution with a nonvolatile solute at the same temperature is given. The ideality of the solution is to be determined. Concept introduction: The given solution is ideal if it obeys Raoult’s law. The Raoult’s law is given as, Vapor pressure of the solution = Mole fraction of the solvent × Vapor pressure of the pure solvent

Interpreting NMR spectra is a skill that often requires some amount of practice, which, in turn, necessitates access to a collection of NMR spectra. Beyond Labz Organic Synthesis and Organic Qualitative Analysis have spectral libraries containing over 700 1H NMR spectra. In this assignment, you will take advantage of this by first predicting the NMR spectra for two closely related compounds and then checking your predictions by looking up the actual spectra in the spectra library. After completing this assignment, you may wish to select other compounds for additional practice. 1. Write the IUPAC names for the following two structures: Question 2 Question 3 2.
