    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 can't ever thank you enough for taking the time to explaining these things with colors, I'm such a visual person that I can't see things if step by step aren't told. Thank you a million and 1 times!!! I will for sure be sharing this video with the rest of my classmates from O. Chem!

    Your organic chem course videos are really good, there is only one thing that might improve the course and that would be to give practice problems like you do on your other courses not just videos. The videos are phenomenal but giving practice would also be very helpful to solidify these concepts and lock them in.

  • @kru1552
    @kru1552 11 ปีที่แล้ว

    They require about 11 kcal/mol of thermal energy. The room temperature has 20 kcal/mol of thermal energy, therefore they change the conformation rapidly back and forth at room temperature.
