Kinetic Control

A condition in which the rate at which reactants are converted into products determines the predominant product, influenced by factors like temperature and reaction time.

HBr

A corrosive, gaseous compound used in the production of inorganic and organic bromine compounds and as a catalyst in some types of chemical reactions.

Dienes
