Question: (a) Draw the product(s) of bromination of this compound, including all expected stereoisomers (if any). Use wedge-and-dash bonds to designate the stereochemistry at any chirality centers, and make sure to draw an explicit hydrogen if a chirality center has one. (b) Characterize the starting alkene as having the E or Z configuration.

Bromination of isobutane is a two-step reaction, as shown below. Using the table of bond dissociation energies, calculate the enthalpy of each step and the enthalpy of the overall reaction. I got the first enthalpy right but the second and the third one wrong.

Answer to NBS bromination of 2-methylcyclohexa-1,3-diene yields. Your solution’s ready to go! Our expert help has broken down your problem into an easy-to-learn solution you can count on.

Historically, bromination of an alkene was done using molecular bromine in a chlorinated solvent such as methylene chloride. However, not only is molecular bromine volatile and highly corrosive (in addition to causing severe burns upon contact with skin and irritation upon inhalation), but methylene chloride is a suspected carcinogen.
