Decalins

[@pantheruni2698]

THIS is just what I wanna know!
Molecule model is really helpful to know stereochemistry.
Thank you for your excellent explanation!

I can't begin to tell you how much this helped. Thank you so much!

[@ronaksingha7152]

Very Very helpful Thanks sir. It would be nice if you would do a video on perhydrophenalene

[@subhajitbiswas9931]

Nice explanation sir 👏

Wouldn't the boat conformation have lower energy for the trans decalin, if there is a bulky group sitting axial in the chair conformation? I'm sitting with the exact same molecule set building decalins...

It's a good question! One I thought I was sure on, but decided to do some checking. I ran some rough molecular calculations and there is still a 1 kcal/mol difference in favour of the substituent (tBu) being axial in a trans-fused chair-chair decalin.

Thanks!

so clear!

Thank you.. This video makes it much easier to understand :)
