The value of the equilibrium constant for a reaction at a particular temperature is given to be 1.7 × 10 − 8 . The presence of a large or small amount of unreacted starting material as the given reaction reaches equilibrium and if the given reaction will be a good source of the products is to be commented upon. Concept introduction: The state when the reactants involved in a chemical reaction and the products formed in the reaction exist in concentrations having no further tendency to change is known as an equilibrium state of the reaction. To determine: A comment on the presence of a large or small amount of unreacted starting material as the given reaction reaches equilibrium and if the given reaction will be a good source of the products.

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.
