    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.

    Thanks a lot. You don't understand how much you are helping people from around the world. I can't thank Khan Academy enough for doing what they do. Keep it up!

    I personally think that Khan Academy is the best source of online learning. When I first encountered this youtube channel i thought for a second. wait "Would I be able to understand,possibility are there might be few terms which might be used in the video which might not be explained or talked about in my reference book" But trust me, it covers every single term and concept. I sometime wander whether he had read my course book or what lol

    At first I was put off by the rough diagrams but you helped me understand this a lil more. Will surely be returning throughout my A-levels! :)

    Ok. I barely studied this entire semester, got 71, 42 and 50 on my 3 tests and 90 on my final. Thank you so much, I literally learned organic chem I in one night, and aced my final. I honestly just dont get it why cant the teachers be like you, you're so clear and your explanations are wonderful! Thanks again Sal :)
