In a periodic table, the group in which the elements possess the highest ionization energy is to be identified. Concept introduction: The ionization energy is defined as the energy that is required for the removal of an electron from a neutral atom present in a gaseous state. When the valence electrons of the elements are closely attracted to the nucleus, the more quantity of energy is needed for their removal.

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.
