Interpretation:
Whether the formula written for ionic compound is molecular formula or empirical formula needs to be written.
Concept introduction:
Ionic compound is formed when there is complete transference of electron from metal to non-metal.

Answer to Problem 24A
The formula written for ionic compound is empirical formula.
Explanation of Solution
Ionic solid contains more number of positively and negatively charged ions. It is represented as simple whole number value. Ions are arranged in crystal lattice so that attraction between the ions is maximum and repulsions are minimum.
For example:
One unit of Crystal lattice of
Thus, the formula of ionic compound is actually the empirical formula.

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.

To check your predictions, click this link for Interpreting NMR Spectra 1. You will see a list of all the - compounds in the spectra library in alphabetical order by IUPAC name. Hovering over a name in the list will show the structure on the chalkboard. The four buttons on the top of the Spectra tab in the tray are used to select the different spectroscopic techniques for the selected compound. Make sure the NMR button has been selected. 4. Scroll through the list of names to find the names for the two compounds you have been given and click on the name to display the NMR spectrum for each. In the NMR tables below, list the chemical shift, the splitting, and the number of hydrogens associated with each peak for each compound.
