Enother interesting information: specially for you.
Discussion
- What do you think about this? see, and tell us now.
- What about the opposite three-memebered ring? Halohydrin from epoxide. While I have read the theory my understanding is that the halogen will be in place of the more substituted carbon since the carbocation will have to form. Whie this is true for alcohols I've never seen such an example for acids such as HBr or HCl (all of them being symmetrical or equally substituted).Sources: Carey, McMurry, March.Edit: Reaction of cis- and trans-3,4-epoxy-3-methylbicyclo-[4.1.0] heptanes with hydrogen halidesÉ. Kh. Kazakova,S. V. Filippova http://faculty.swosu.edu/william.kelly/pdf/ch18.pdf Another example but it does lack sources.CheersEdEn
- Will halohydrin formation via this reaction mechanism always occur via anti addition? Thanks. Again great videos.
- at 5:08 is it also necessary to draw another curved arrow from the Cl atom to an alkene carbon to show that two bonds are being formed to that chlorine atom?
- A quick search of your videos indicates no further information of epoxides o halohydrins. Being these educational videos I left 2 links on my previous post for you to leave an annotation on the video itself regarding the question asked there, even though it belongs to another series of reactions, that epoxides and not alkenes but am aware all text books put such topics next to each other or as a subchapter.
- Thanks! I've watched a couple of your videos and I have been struggling with Ochem terrible, but these have helped. :)
- you are very welcome
- Thank you Graham
- You deserve an award. These trump all other videos and sites!
- There's a difference between the temporary and partial charge on the neutral CL2 molecule compared to a full chloride ion in solution. The partial charge happens when the pi bond gets too close to the neutral halogen molecule as it starts getting attacked. Hope this clears it up for you
- Really, so clear and concise. I missed a week of class (flu, awfulness) and I have a test Thursday. I genuinely feel prepared and confident. Really, really great vids.
- Just beautiful. Thanks so much for the video! You mentioned that the Cl- ion will be surrounded by the partially positive H+ ions in water, thereby preventing it from interacting. When Cl2 exists you also said that there is a partial positive and partial negative charge in that molecule. Why would water not just surround both and prevent either of them from interacting? Thanks!
- glad you're feeling better and that my videos helped :)
- I love you , im forever in you dept you have my respect like and subscription
