Alkene reactions are the foundation for all future organic chemistry reactions and mechanisms. To help you build that solid foundation I've put together this short quiz testing your knowledge of reactions, reagents, products and additional molecule concepts.
These questions range from medium to tricky and should be completed AFTER you've studied my Alkene reaction video series since each video already contains a few simple practice problems.
Take your time and think through each question. If you're not sure how to proceed click the ‘hint' link for the related mechanism tutorial video. Once finished scroll down and grab a free copy of the solutions.
