The more rapid reactant has to be identified. Concept introduction: Carbocation: Carbocation is a positively charged species and vital intermediate in organic synthesis and its movement depends on the stability of the intermediate and the product formation. Hydrobromination: A hydrobromination reaction is one of the electrophilic additions to alkenes to yield the corresponding bromo alkanes. In this reaction the bromine atom adds to the double bond carbon which is having lesser number of hydrogen or more substituted carbon ( Markovnikov's rule ).

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.
