Thank you leah, even on this side of d world (World), d impact of ur contribution is still felt, Im in org 1 and woooo you just saved my semester! This video walks you through all 3 reduction reactions – to alkane or cis vs trans alkene, as well as a step by step walkthrough of the radical reduction reaction mechanism for alkyne to trans alkene. Introduction to reaction mechanisms (Opens a modal) Markovnikov's rule and carbocations (Opens a modal) … In many cases, the mechanisms of these reactions will proceed through a carbocation mechanism, which means we should have a discussion about Markovnikov’s rule. Send link to Alkane, Alkyne, Aromatic notes pls, You’re welcome! =), thank you so much for your videos n for sharing your knowledge and experience with us. THANK YOU TO THE MOON AND BACK :))), wow am loving your video and where are you located I need to join the organic chemistry hall for help because I’ miss sometimes what the professor says sometimes, Thank you Gloria. Alkene reactions. Science Organic chemistry Alkenes and alkynes Alkene reactions.
How do we know that this process does not occur?
No more “gotta watch 5 different videos just to understand 1 topic.” Thanks so much! Alkynes have a triple bond allowing for more complex reactions than their simpler alkene counterparts though the reactions are quite similar. Thank you!
If so I have one here: http://leah4sci.com/alkyne-reactions-organic-chemistry-cheat-sheet/, I really appreciate your you-tube videos that completely describe the reaction mechanisms for alkenes.
Yu Shibata and Ken Tanaka of the Tokyo Institute of Technology effected * Weekly emails from your personal Sherpa, telling you what to study with links to find it, save you study time. Reactions of Alkenes Alkenes, and in particular terminal alkenes, are readily prepared (e.g. Understand peroxy acid (mCPBA and peroxyacetic acid).
Alkyne reactions are yet another critical tool in your organic chemistry arsenal. Thank you so much for taking the time to create all of this! This occurs via a cyclic bromonium or chloronium intermediate.
So this is a reduction reaction. Thankyou so much for making organic chemistry intresting……loved your videos….as well as ur voice….. what appears to be a general protocol for the anti-Markovnikov addition of HBr to an

Do you have any information on writing condensed formulas for aromatics (benzene, toluene, phenol, aniline)? Instead use this guide as you study to ensure that you understand mechanisms and recognize reaction sequences. The typical catalysts for the alkene hydrogenation are the platinum (Pt), palladium (Pd), and nickel (Ni). Alkoxymercuration-Demercuration Reduction is the alcohol version of the oxymercuration reaction.
This reaction starts out just like the halogenation reaction, but since it takes place in a reactive solvent, you get a solvent molecule partaking in the reaction mechanism. Cheers from UK! Kilian Muñiz of ICIQ effected Chem.
Leah, your simply AMAZING.. Keep doing what your doing.
If you enter "oxymercuration" at Search on Chemistry at the top of the page you will find a wealth of information at your disposal right here on ChemSE. Alkene halogenation. Did you attempt the alkene quiz yet?
The video below is a walk-through of the above cheat sheet explaining the reaction tricks and shortcuts.
* 24/7 access anytime, anywhere on any device, to study on your time. I want to see whether such reaction will add seperate glycol on each carbon of the double bond, or the glycol will form a cyclic with the two carbon of the double bonds? A decrease in the oxidation state means a reduction.
Thank so much!
Many thanks again.
It only takes a minute to sign up. I was wondering what would be the product of the reaction of alkene with a diol (such as glycol) in alkoxymerucuration/demercuration, i.e. 2016, 18, 2722. What are the products formed when CH3CH2OH reacts with NaH? 2016, 7, 3031,
Thank you for this!
So the alkene is reduced by the addition of these two hydrogens. I see no reason why you would get di-addition to the alkene.
Formation of mercurinium ion 4 with mercuric trifluoroacetate (2) is drawn as unsymmetrical because in the transition state for addition the carbon bearing the greater positive charge is the site of SN2, C-O bond formation. In this video you’ll get a proper view at the pi bond orientation and how this relates to alkene reactivity. Rafeala not quite. Asian J. A several billion dollars project to stop people from sneezing, besides full hazmat suits?
The product of this reaction is an ether as detailed in this tutorial video.
Which topics are you studying right now?
Heat is used to catalyze electrophilic hydration; because the reaction is in equilibrium with the dehydration of an alcohol, which requires higher temperatures to form an alkene, lower temperatures are required to form an alcohol. [With free chemistry study guide]. Hydroboration-oxidation: Mechanism.
After all of that, he (briefly) worked as a post-doctoral assistant at Syracuse University, working on novel organic light-emitting diodes (OLEDs). 1997, 62, 9342. Reactions of alkenes Like the alkanes, the alkenes undergo combustion. the amination of 8 to 9.
Alkene reactions are the core foundation to learning reaction mechanisms in organic chemistry. The true key to successful mastery of alkene reactions lies in practice practice practice. What are the products of the reaction of methoxypropane with HBr? I will keep following the link for more information on rearrangement reactions.

You can't afford to waste precious exam time calculating formal charge. How to make this illumination effect with CSS. Therefore I presume in the presence of a diol you get mono-addition by one of the 2 available OHs, probably the least hindered. I'm thinking if these possibilities (I have more possibilities in my mind, but for example I selected three) are structurally accurate and energetically stable to be produced in such reaction and which is favored?
I don’t have anything for alkanes on YouTube. Start here to get grounded with alkynes as you prepare to tackle more in depth reactions. The chemistry works because there is a ton of electron density within the pi bonds of the double bond. specific to alkenes are therefore of particular importance. University of Delaware. Thanks Karen. Surfing web came across your tutorials. This video walks you through the alkyne hydration reaction and mechanism. @Waylander I updated the question with single and di-addition possibilities, I'm not sure if excess of glycol or other factors will move the reaction toward single or di-addition or toward open or cyclic formation in either case. These are likely the first set of reaction mechanisms covered in your Orgo 1 course. I focused on the main reactions that require simple mechanisms and then moved on to another series that students were asking for at the time, The true key to successful mastery of alkene reactions lies in practice practice practice.

Why is it that on this sheet, the Hydrogenation (H2/Pt) of an alkene is syn-addition where as on you sheet for Oxidation + Reduction, the alkene reduction with (H2/Pt) is anti-addition?
* Study plan with links to the material, based on the grade you want. Mastered the basics?
This is a slow and lesser favored method, used primarily for internal alkynes. I’ve watched other videos and that’s what it seems to be but here you have them in opposite directions.
glad you’re enjoying them, Wow I just found your site by watching your tutorial on YouTube and it was helpful in my study.
Thank you SOOO much, you are amazing!!!!! 2016, 138, 5539. (J.
This mechanism typically involves hydrobromination and hydrochlorination in an inert solvent. You are so helpful, thanks for having a lot of free resources! Passively watching videos is NOT enough. Alkenes, and in particular terminal alkenes, are readily prepared
