Chemmunity 🤣

[@alinakati1993]

Since there's no equally fantastic OC Channel in german, I always watch your videos and its sooooo cute how you pronounce the german words in this one haha. Keep up the good work, you're great!

[@ProfessorDaveExplains]

haha why thank you! my dad lives in Aachen say hello for me :) and feel free to correct my pronunciation, i want to be authentic!

[@thepassion1243]

Professor Dave Explains hello Dave can you do some tutorial in stereochemistry models and mykayama and Suzuki reaction

[@onslaabidi5254]

haha i thought the same especially Zusammen

[@borwinbandelow2781]

I had no idea that the origin of E/Z really is german... I thought its just a crib from our chemistry teacher xD

[@arandomcatwithagun2680]

I'm so glad that i can learn chemistry from Jesus.

[@ThePanEthiopian]

Straight from the source

[@jchae9820]

a medical student who's forever thankful you are GREAT sir

[@reikunwar174]

You explained a thing in 6.00 minutes what my professor wasnt able to do in 2 hours and still i undertood more during this 6 minutes than i did during the 2 hours. Thank you!

[@valeriemel4887]

Just discovered theses OC videos and you do such an amazing job! Not only do you explain the topic clearly, but you answer all the questions, in advance, that I may have. You're super enthusiastic and these videos really did help me a lot!! Thanks Professor Dave :)

[@mirelaratu3113]

I am a romanian living in Italy and I watch your great videos that are such a fortune to me! Thank u

[@Xannypack2]

the first half of my semester in organic chemistry was so difficult :( now that i've found this channel all those lessons now seem easy. Thank you!!!

[@DaLokNessMonster]

I watch your videos because I love your lil intro , you also explain things so well thanks a lot!!

[@Evendur96]

The E/Z nomeclature is the first thing in chemistry I saw where it helps to speak german :D And thank you very much, there aren't any good videos about organic chemistry in german ;) And btw, the way you pronounce "entgegen" sounds very authentic but the Z in "zusammen" is a bit too soft (as it often is used in the englisch language), but in german language, it sounds more like "tsusammen" if you know what I mean :D

[@ProfessorDaveExplains]

haha i will work on it!

[@willichnichwissen]

it is sooo sweet to hear you say "susammen"! so, dont change it ;)

[@midnight5142]

Something that my professor took 2 50 minute lectures to explain you did in 6 minutes and made it much more clear. Thank you sir.

[@hawraaarkan8300]

6 years later & I am still learning from your KZbin channel , Tank you

[@EmilyBenson1998]

You’re the best chemistry professor on KZbin!

[@lilynichols5208]

Thank you so much for taking the time to make these videos! Some of the other youtube videos that exist out there simplify it a little too much and I still don’t understand the complicated terminology that my professor/ book uses, but you use that nomenclature while still giving an in-depth explanation making it easy to understand!

[@lucasmabokomabudu3331]

your videos really helps me to understand the chapter before i go into the study guide or any study material keep up the good work....may God bless you.

Thank you so much for this video, sir. I was so confused while revising this topic and your video helped immensely.

Yes, my bad.

This made perfect sense, and made a concept I thought was difficult seem easy! Thank you!!!

[@DerDrako]

For me as a german, E for entgegen and Z for zusammen, were just ideas in my head to remember the letters. Awesome that the realy derive from these words. :D

[@michaelleonardlubiano3912]

Thank you Prof. Dave for helping me to understand the E/Z alkene easier. Thanks!

you made this so easy to understand thank!!! literally found your channel today and its gonna save my ass with my midterm coming up

Thank you so much for your work. Zeezamezide, I'll never forget that :D

[@ariellep5665]

Thank you for the very helpful video! I now understand how to assign E and Z configuration! Do you have any suggestions for determining when a product demonstrates neither configuration? My textbook swears this is a thing, but I can't seem to figure out how anything could be neither E nor Z.

[@ProfessorDaveExplains]

Sally P the only way E/Z wouldn't apply would be if an alkene is monosubstituted or completely unsubstituted. as long as there is at least one substituent on each carbon, E/Z can be assigned.

[@MTRiderJanis]

you explain great! Even I (I´m from Germany) can understand it although I´ve never learnd some of these technical terms :) thank you :D

[@kass1663]

Taught me more in 6 minutes than my uni prof taught me in four months...
