[@soumyasharma5743]

WOW!! I love your energy Richard! You are AWESOME!!!

[@nayelnayel865]

I think you're my favorite chem teacher, ur my only hope in chem ib

Used this for IB and now, a year later, using it for University! Awesome

[@annaschusser9661]

This was honestly so helpful! Thank you so much.

I have one question: Why is there no rotation around the double C=C bond? Is that true for all double/triple bonds?

[@vankshubansal6495]

Nikki Odenhoven yes. only sigma bonds can rotate.

[@thefirem4ster864]

P orbitals overlap sideways. They would have to break to rotate. Sigma bonds, made of hybridized orbitals, can rotate.

[@thefirem4ster864]

Can we use skeletal/line structures on the IB exam?

[@ibchemvids]

I would avoid it unless asked to. Stick with structural or condensed structural formula.
