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.

easy and clear way of lecture, thank you
Wonder ful..made it easy
I finally understand this now. Thank you! =p
At 11:20 you explain how the sec-butyl comes from the secondary carbon and ignore the third on the alkane, but at the end of the video on the cycloalkane molecule you call the same sec-butyl carbon tertiary. Which is it?
thank you so muchhh
Very interesting 👌
why is the molecule to the left @ the 3:47 considered 1-methylpropyl? shouldn't it be considered butane?

+Adam Thedon When you start numbering the carbons you have to start from the carbon attached to the original chain. From there he went to the side with the longest chain which was a total of 3 carbons(propyl) with one substituent which was the methyl on carbon 1.
at 6:16 why isn't it 2 methylbutyl? That's the lowest number for the substituent ? You did that for the explain before why didn't you do it for that one?

With side chains such as these, the #1 carbon is the one that connects to the parent chain, which is what the zigzagged line is.

yea cought it too... and happy that encountered with ryan answer!
🙏🤝
why is it 1-methyl ethyl ? according to the rule, we need to go with ethyl first ?

The methyl is the branch of the ethyl branch. Think of the ethyl branch acting similar to the main branch with the methyl group sticking out. If you had hexyl branch which also had a methyl branch and an ethyl branch then I think the rule applies. Correct if Im wrong
Y 1 methyl ethyl
i thought iso meant different
😑
2:05 can't we name it 4proply haptane?
Who's here??? 2023
