      Thank you so much for commenting. It makes me very happy that my goofy saying helped you on an exam.
      Leah4Sci helped me so much when I took Organic Chemistry, so you have found an amazing resource.
      I would encourage reaching out to her directly and signing up for her virtual study group. Being able to connect with other students studying this material was extremely helpful. I wish you the best in your Organic Chemistry endeavors for whatever you are studying. "Break a pencil" on all your exams too!!! ;)

    something important to note: for the syn metal additions, the added H's (or D's) will both be a dash or a wedge. youll end up with at least 2 stereoisomers in which the dashes turn to wedges and vice versa.

I had semester pass and I don’t regret a penny I gave for the access. I am now retaking Orgo (took it for N/C past semester because I didn’t understand nothing after few first chapters) and I see all with different eyes, and a better brain.

    Can someone explain why an addition to create an alkyl halide always forms with halogens on same carbon (geminal rather than vicinal).

    • @Leah4sci
      @Leah4sci  Рік тому

      I assume you're talking about the hydrohalogenation reaction. It does produce a geminal dihalide when the reagent is in excess. The reason for this placement lies in the mechanism, which proceeds via a carbocation intermediate. A secondary carbocation is more stable than a primary one.
      Since I have not made a UA-cam video on the alkyne hydrohalogenation, watch the following alkene reaction mechanism. And then imagine how it would happen TWICE for both of the pi bonds in an alkyne. ua-cam.com/video/gYOIQ0zTigQ/v-deo.html

    • @Leah4sci
      @Leah4sci  5 місяців тому

      That reaction is not covered in this video because LiAlH4 is not primarily used to reduce alkynes. In fact, it will only do so if an alcohol group is nearby. LiAlH4 is used to reduce things like esters, carboxylic acids, and amides.

      Thanks for your feedback. Have you tried slowing the video down using the settings button below the video? Set speed to 0.75 or 0.5 to make it easier to follow.
