    Organic Chemistry on Khan Academy: Carbon can form covalent bonds with itself and other elements to create a mind-boggling array of structures. In organic chemistry, we will learn about the reactions chemists use to synthesize crazy carbon based structures, as well as the analytical methods to characterize them. We will also think about how those reactions are occurring on a molecular level with reaction mechanisms. Simply put, organic chemistry is like building with molecular Legos. Let's make some beautiful organic molecules!
    About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

    I just don't understand why the lectures in the uni can't explain the concept in simple language. They have to make them confusing to trick the students. Love Khan!

      I hope Khan can help you put your love to practical use. Perhaps you'll merge your knowledge of organic chemistry with your current occupation.

      Yes I would certainly hope so, I was thinking about Sn2 reactions on the round today! There is one house that I always get alot of broken glassware to collect, he has a BMW with blacked out windows, he sometimes bungs me a bit of cash, he seems to be doing well in life, maybe I ask him about organic chemistry...

    Quick question: why did Sal draw the C-OH bond on the same side of the Br ion was at? Wouldn't there be steric tension that prevents the OH from entering on the same side of the Br?

    Why are there three videos of this with the SAME example??? All of your SN2 videos (that I've seen, so 3) are where the nucleophile and leaving group are in plane, can we see examples of when the nucleophile and leaving group aren't in plane? Also maybe just see different examples too?

    but i couldn't understand the difference between sn1 and sn2 reaction. They seem to be the same. Could anyone please help me understand the difference?

    • @techforever1970
      @techforever1970 Před 6 lety +3

      There are many differences, and due to me being lazy, ill give you a couple or more. the first is that SN2's rate equation involves both the nucleophile itself and the the alkylhalide, whereas SN1's rate equation involves only the alkylhalide. SN2 is only one slow step, whereas SN1 occurs in two steps, one fast and one slow. SN2 requires a strong -ve nucleophile, vs the another nucleophile for SN1. Hope this helped even if a little bit.
