D7 Describe the use of chiral auxiliaries to form the desired enantiomer [HL IB Chemistry]

1) Drug manufacture can produce both enantiomers (pair of related chiral molecules), but often only one is needed -- the other is toxic (eg thalidomide)
2) It is time consuming and wasteful to separate the enantiomers after production -- better to only make one of them in the first place!
3) A chiral auxiliary is used to bond temporarily onto the reactant so that only one enantiomer is produced -- this auxiliary is then removed and reused.

This must be one of the best representations of an otherwise difficult/complex topic I've ever encountered. You make teaching look easy! Thanks!

[@fredrick3242]

We are definitely in a new era of teaching. This is great.

Thank you so much mr thornley. You're videos helped me on paper 1&2 finals today.

Just trying to add to my Personal Statement about how interesting enantiomers are for phramaceuticals and found this fantastic gmod representation. This is amazing, thanks!

[@agulamhussein]

This was just amazing.

[@ZGwoo888]

loved this great representation

[@shenthomas2689]

mate you are genius!!!

[@HuwsAppReviews]

awesome

[@bungkus02]

What game is this Richard? As a fellow teacher, hats off to you, this is amazing work. Students will definitely love this!

[@ibchemvids]

gmod!

[@gogetaSSfive]

I'm not even interested in physics and learned something today

[@eminglee7716]

gogetaSSfive and this aint even physics *-*

[@gogetaSSfive]

And now I've learned something else!

Hi! I was wondering to what extent these videos apply to the current syllabus? They are great!

[@ibchemvids]

If I recall - the ones in the playlist do - others you find via search do not.

[@linae9601]

@@ibchemvids great! Thank you:))

Hey Mr. Thornley! This comment is actually for the next video, the one about the effects of psychoactive drugs, but comments were disabled for that video. You said you had some trouble researching, and I'd just like to link you to a site that explains the neurological aspect (and thus some of the physiological effects) of some drugs. KZbin won't let me put in the url, but just Google "Mouse Party drugs". You should get it. I've found it pretty useful in biology. Hopefully you can use it!
