Among the two given acids, A and B, the acid that is more acidic is to be predicted. Concept introduction: For the given acids, the stability of the conjugate base dictates pKa. Conjugate base of an acid is stabilized by electron withdrawing groups near the negative charge through electron withdrawing inductive effect. The more the electronegativity of the electron withdrawing substituent, the more is the acidity. The stability of the conjugate base decreases as the number of electron donating groups near the negative charge increases.

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.
