    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.

    Nice. Good explanation of the mechanism, step by step (extra points for color-coating ;D )

    Thank you for the videos they are great. If you could make a play list of all the reactions, synthesis and mechanism videos I think it would help me not have to search through all the other videos that you have up.

    2:16 why phi electrons attack the unchanrged oxigen instead of the positively changed oxigen in ozone. Thanks.

      Maybe to make cycle?

    • @karthikkd3471
      @karthikkd3471 3 года назад +2

      Nucleophilic attack on central oxygen is not possible because of steric Hindrence of two oxygen atoms around it which also have lone pair of electrons and it means electron cloud around it which leads to repulsion of pi bonded electrons which attacks the oxygen but in the terminal oxygen (if you look at the resonance structure positive charge is possible in terminal oxygen by giving the pi bonded electrons to the central oxygen) it is possible.. so it happens like that...Hope it helps😊

    at minute 4:30 when you write the structure (CH3)2 -- C=O-O there is a separation of charges and a positive formal charge on oxygen , my book write that as CH3 -- C(+) -- CH3 and only single bonds on oxygens (the last one has a neg formal charge) that that put a positive charge on the secondary C that became a more stable secondary carbotanion. Dou you agree with that?

    At 2:16 why the double bond attacks oxygen on ozone instead of carbon next to it

    After ozonolysis of alkene......ozonide is obtained.....then how to reduce ozonide....????

    • @agent475816
      @agent475816 8 лет назад +1

      +hamza khan Using the reducing agent DMS (dimethyl sulfide) (CH3)2S. There are more. You can add peroxide for oxidation to a carboxilic acid.

    Why does the rxn start with an attack of a neutral oxygen? Shouldn't it start with the attact of the positive oxygen? "Necleophile to electrophile"?

    What happens if the molecules are not symmetrical something like 1-methylcyclohexene?

    • @agent475816
      @agent475816 8 лет назад

      +Dylan Dautel For that, you are going to get 6-carboxylheptanal.

      Becoz of random electron cloud shifting

    Just a terrible explanation for tests LOL, let me explain this in a 30 second read. Whenever you see O3 you have to cut the double bond in half and just put two oxygens at each end from the cut double bond LOL!! Like C=O with O3 will be C=O plus O=O. looollz
