E/Z Alkenes, Electrophilic Addition, & Carbocations: Crash Course Organic Chemistry #14

Alkenes are an important type of molecule in organic chemistry that we’re going to see a lot more of in this series. But before we can really get into the many cool reactions alkenes do, we need to go over some of the basics. In this episode of Crash Course Organic Chemistry, we’ll review and build on our knowledge of alkene nomenclature, revisit our friend the carbocation, and learn Markovnikov’s Rule: an important tool that will help us predict the products of addition reactions involving alkenes.

Just a day after I took an exam on this...

[@shelbieht5360]

Don't even study chemistry I just want to be more aware and knowledgeable

[@lessgogeezers]

KZbin recommended me this 1 day before chemistry exam. Damn, even KZbin cares more about me than I do.

Honestly the part when she says, "okay, deep breath" is so real.

If you are on a unicycle, your best bet is to practice from a wall. When you fall, the unicycle likes to shoot outward, which could hurt one of your friends.

I read that you have to have IDENTICAL groups on each side of the double bond for it to be cis or trans, but that's not what you are showing here.

I've been following several chemistry channels (NurdRage, NileRed, Explosions&Fire) and this series has really started to connect some of the dots when they talk about the reactions they're doing - thanks so much for these videos!

[@anjulovesdoracakes22]

First comment!!! I'm currently studying chemistry and didn't understand organic chemistry so well, but after this series, I understood it nicely!

[@rambles2727]

For those confused by later episodes come back to this one and pay attention to markovnikovs rule

[@bleuemoone8710]

Could have used this series back when I took ochem but now I'm in biochem so is probably useful still!

[@zayrael]

Absolutely amazing video, the animations help SOOO much and the concepts were explained so well! Made for a great review. Thank you CC for once again carrying my OChem grade.

[@maglo8]

So I’m actually a PhD chemist who mainly does organic chemistry. I watched this in the hope to see if E and Z isomers have different reactivity to HBr. That topic was unfortunately not mentioned….

[@vaughnjohnson8767]

“We can use the Ez method.”

[@diegoroman7092]

This video was pretty good. Understood some bits and pieces of my lecture today, but this video connected all the dots. Thank you!

[@ShirinRose]

I'm from the Blue Mountains in Australia! So cool to see them featured here 😃

[@Swuirrell4days]

Time to learn

[@yahav897]

Hey, CrashCourse, love the videos. I'm not sure if it's been discussed already, but are there any plans for a mathematics playlist? I'd like to see that.

Not "on ze zame zide" 😆 I will remember that for the rest of my life!

[@Thanos-hp1mw]

This is definitely one of my favorites of crash course.
