Question

Consider the addition of HBr to 2-pentene. Indicate the re

andsi faces if 2-pentene. Draw any possible products from
thisreaction and indicate whether they are R or S
configuration.

Answer 1

This addition reaction yields 3-BromoPentane and 2-BromoPentane.

Explanation: The reaction is an addition reaction that follows the Markonikoff's principle engaging the electrophillic addition mechnism with electrophile having no lone pair so rearrangement of carbonation is possible. It yields two possible products.
