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.

One small point on the generic/formula drawing of the acyl/acid halide: It should be R-C(O)-X to not imply that it must be a chlorine.

Very helpful!!

Amazing teacher

1:10 why would it be butane if the last carbon is part of the aldehyde group? Shouldn't it be propyl aldehyde?

@aayhabdelgawad1382 9 лет назад

+agent475816 You never end it with aldehyde..Also there are 4 carbons it cant be propyl.. The final name is butanal .. the al at the end indicates an aldehyde group. Hope this helps.

@agent475816 9 лет назад

Ayah Abdel Yes it helps. I just thought that the group (CHO) is the aldehyde group and the carbon doesn't count when you're naming it. That's why I thought it would be propanal.

@@agent475816 They easily could have done that instead since the carbonyl carbon is considered part of the functional group. They chose not to, maybe because it would you with methanal as CH3C(O)H, and then you have no meth/eth/prop/but names for formaldehyde, C(O)H. Instead, we consider the carbonyl carbon to be both part of the carbonyl group and the main carbon chain. This fixes that potential naming inconsistency. You also would h ave a conflict with naming if you performed a reaction that changed that aldehyde group. You'd be changing a 2-carbon "methanal" into a eth-something, 2 different carbon-counting names with the same chain. I know this is 4 years old, but I hope this clarifies for anyone else who sees the same possibility and wonders why it's this wayy.
