Free Radical Reactions


By The Organic Chemistry Tutor

This video provides a basic introduction into free radical reactions. It explains the reactivit-selectivity principle between Chlorine and Bromine and it explains how to calculate the relative percent yields of each monochlorinated product. It discusses heterolytic and homolytic cleavage as it relates to the formation of radicals as well as how to identify initiation, propagation and termination steps in a radical reaction.

Example: Complex roots for a quadratic | Algebra II | Khan Academy


By Khan Academy

This video shows us how to use the quadratic formula to find the roots of a quadratic equation when those roots are complex numbers. Apply the quadratic formula as you have before, but be very careful when simplifying the radical part of the formula. And, as always, double check that you calculated the number under the square root (called the discriminant) correctly! Most mistakes with the quadratic formula happen under the square root!
