Organic chemistry: R and S naming (1)

[ja50gurl911]

This guy needs to be working at one of the top universities, getting paid bank, he definitely deserves it more than the douchebags that are currently teaching.

[bs0u31c3]

Thank you so much

[Chilenopart]

This is what a REAL o-chem teacher should be like. The others can stay with their research, but for the love of God stay out of the classroom if they can't/don't want to teach.

[sekulabane]

Thanks man a lot, you helped me in many things I just couldn't understand in OCH, now it's much easier and I find it interesting :). Greetings from Slovakia :)

[WizkidKumar]

Keep up the good work!

[630399]

N is "3" and O is "2" how lance labeled it. Right?

[630399]

I take that back



[630399]

N is "2" and O is "3" how lance labeled it. Go and check it on the periodic table. Right?

[rockin198]

Lol thats true i can never understand my professors but when i watch youtube videos i get it thank god for youube always being her e

[rummy389]

While watching these videos, I find myself repeating the phrase "WHY DIDN'T MY PROFESSOR JUST FUCKING SAY THAT!?!" Thanks man.

[ameneteid]

@rummy389 so true or maybe i understand anyone on youtube except for my professor.

[DiLLyDaLLyHo]

What is that scratchy green surface on which he makes the strange white marks?

[blackyspy]

@DiLLyDaLLyHo its a green board lmao, he used chalks to write on it .dosnt exist alot anymore

[MrDeathslash]

you are officially my chemistry professor from now on :)

[Kunglao63]

See if the professors at my college were like you I'd have a higher grade but sadly that is not true. Thank you for your time and effort in making this video.

[trust143raj]

If i make an A in my exam, am certainly donating you at least 20$.

[MrNatty513]

Thank you so much! Chemistry is fun once you know what's going on

[egghead068]

thanks man you helped me a lot

[jeevarajiit]

ur videos are really rocking...plz upload more videos...my request is to upload maths videos also plz plz

[gmgunner]

Thanks alot, these videos helped alot.

[MsEyeBubbles]

cant you just take my test for me :<

.

.

im just kidding guy, keep up the great work! :D

[Bob8199]

This guy is smart and educated. He's definitely a dying breed. Today's generation of young adults believes being smart and educated is not only uncool, but also a waste of time.

[ironbull2003]

@Bob8199 Considering colleges are overflowing with students and it's 10 times harder to get into any college nowadays than it was 10, 20, or 30 years ago... your statement is rather stupid and false...

[Alaznel]

@Bob8199 HAHAHAHA coming from a guy who's favourited vidoes of chicks with big boobs with comments like you'd like to fuck them, you sir aren't exactly the best judge at how smart this young generation is.

[scuzzulus]

sweet.does this guy teach at university or high school level?  i assume its college students...

[ayyjay69]

that is a large eraser

[Igglesnoop]

@ayyjay69 Hahaha.

[RizzalVixen]

i will make sure to donate to your website. but if i pass my organic chemistry class this semester, im donating $100. its more than worth it

[albertho710]

Clear explanation . Really helps a lot , thank you so much

[worship7leader]

I really appreciate your help!!

It has helped me alot.

[gymrat3e8]

If you like using tangible chemical models and you don't have access to one, you can get a page of paper and tear into two strips.. then twist them into little "ropes". Then, tie them together so they resemble a carbon with 4 hydrogens on it (or whatever other atoms you want to pretend..). Then you can label them 1,2,3,4 and you have a 3d shape ;)

[gymrat3e8]

everything i needed within 1:09. awesome! Thanks. 

MedChem Final, Here I come!!!

[rebelxasylum]

Thank you. Thank you. Thank you. I can't visualize at all. I have a take home exam to complete by 10 am tomorrow and my uncle just passed away and I can barely focus as it is. This video has been a godsend. Thank you. 

[cosmogang]

My Organic Prof. is a total Douche Bag.

[ASSHOLELA]

Whats the diff between RS and LD conventions?

[amazingness818]

thank you so much, would really appreciate if you could put your videos on Itunes

[Demonmack0]

Thanks!

[mitrysalehi]

[JohnRater]

Great refresher, thank you.

[danielkirk1]

Is there anything Bill Gates doesn't know?

[greenholic123]

Thank you so so so so so so much. Please continue making more videos of lessons, because you expose the information in a very easy and non boring way

[savedbylove131000]

[Sameer3292]

Here in my country, we wear bow ties vertically !! :] .

[DelPiero9]

@Sameer3292 Where are you from?

[bianca20109]

@Sameer3292 are you really talking about a bow-tie ?? i think you mean the kravate :)

[Werwolfwer]

well, i don't wanna be picky here but if u draw an ammonium group dont forget to put the formal charge (+) on the nitrogen ...he probably meant a amino group and so it is forgiven cause its not essential for explaining stereochemistry

[inspiredbyheaven]

your so great lol thanks so much

[greenclouds80]

Thank you very much!! This is really helpful

[justbequiet1]

This is great. I wonder how you do it and make it so easy!

[bublegumdiva]

can you uplease show us how to draw fischer projection from dash and wedges molecules + newman projection

[MsGrammarnazi]

You are really awesome!

Thank you soooooo much!

[StormZephyr]

The Fisher projection in wedge and dash form looks like Dr. Robotnik's mustache.

[annbug20]

Thanks so much, you explain so well, you repeat and go slow and are very patient.

Thanks, your videos have helped me understand chemistry.

[gjeak]

Hey man, just wanted to let you know that I really appreciate these videos. They have been extremely helpful in learning the often confusing O chem material.

Thank you much

[AliyyahJN]

Your video is soo helpful!!!

Please tell me how I can convert a molecule that is shown with wedges, dashes, and straight lines into the mechanical method. Pleease need help before test on 5/4/09.

[fallenstarx3]

Thanksss!!!

[bublegumdiva]

can you please make more videos on organic chemistry? thank sm..your video helps alot..

[LeeDiddy990]

thank you so much Stereochemistry seemed like a really hard concept but you make it seem so simple that my homework has been cut in half. yes my visualization skills are not that great so yes this method really helps.

[OMNAIA]

can you make a video on reaction? =[ please?

[SqueegyBuckenheim]

Thank you! These videos helped me a lot for my test! You explain very well, thanks for sharing!
