For the related reaction below, circle the product you would you predict to be the major product. The major product is predicted by the Markovnikov rule, which states that when a hydrogen halide is added to an asymmetrically substituted alkene, the major product results from the addition of the hydrogen atom to the double‐bonded carbon that is attached to more hydrogen atoms, while the halide. Becoming a successful product marketer and establishing the function as the value and growth engine for the company starts with you. As NIH’s website states, “Therapeutic development is a costly, complex and time-consuming process.
