mechanism of amide formation with DCC 

Clear an concise. Well done sir.

I love organic chemistry when it's taught well. May God bless your works so you help many students out. Keep it up, you can be like the Organic chem tutor I know it. Advice will be to start making videos with more examples but don't change your techniques.

This was super helpful, but just a note, you left out a methyl group that was originally on the R group of the carboxylic acid during the tetrahedral formation step. Thanks for posting this.

Thanks! This really helped me out a lot!

Seconded! Really informative and clear, thank you!

Mechanism well understood..Thank you Sir

Thank you! You made it look so simple XD

you are a hero good sir

THANKS a lot ! My guess is that the EDC/NHS aktivatoin ist similer? the main reactiv group is the same R1-N=C=N-R2

thanks

Crc!

you have forgetten to draw one of the methyl in final product :D edit : ok i didnt watch last 10 seconds. sorry :P

Rrc rrrcc!
