Introduction to Reaction Mechanisms, Alkenes and Alkynes, Organic Chemistry

In this substitution and elimination reactions worksheet, students compete reactions by drawing the structural formulas for 18 reactions. If no reaction occurs, students write N.R.

Markovnikov's rule is explained in the context of pent-1-ene and Hydrogen bromide. There is a review of electronegativity, which is helpful for viewers, and a recap of how valence electrons behave. The explanation for Markovnikov's rule...

This video builds upon the previous topic and explains how the elimination reaction between moderately electronegative molecules is controlled.

An advanced chemistry class will understand Sal's reaction and see his logic in explaining the equilibrium. The levels of electronegativity and likelihood of a nucleophilic attack are balanced and presented in the equation. This is an...

Get an inside look at the reaction to hydrogenate an alkene in this video. Learn how this reaction is a syn addition of hydrogen. Also look at the oxidation numbers and stereochemistry that result. [11:41]

In this alkenes and alkynes worksheet, students name six structures using the IUPAC naming systems and they draw three organic molecules. They also answer a question about a chemical reaction using the Markovnikov rule.

See different methods for reducing alkynes to alkenes or alkynes.
