161 Conjugated Systems and Heats of Hydrogenation Organic Chemistry

In this lesson Chad introduces conjugated dienes and how conjugation lowers the energy of the pi electrons. This can be seen when comparing heats of hydrogenation. He begins by comparing relative heats of hydrogenation between conjugated, isolated, and cumulated dienes. But he also shows how an alkyne will have a higher heat of hydrogenation than any two alkenes. Finally, Chad gives a list of five rules for comparing heats of hydrogenation and works eight examples to show how to use these rules to predict relative heats of hydrogenation. • If you want all my study guides, quizzes, and practice exams, check out my premium course at https://school.chadsprep.com/subscrip... • 00:00 Lesson Introduction • 00:56 Conjugated vs Isolated vs Cumulated Dienes • 06:06 How to Compare Relative Heats of Hydrogenation • https://www.chadsprep.com/
