I wanted to start a thread specifically for questions on TBR. I hope it's helpful .
So I'll start,
I came across a practice questions that said "In both the E and Z isomers of an alkene, the atoms directly bonded to the alkene carbons are all coplanar"
The explanation says "Because the two p-orbitals of the pi-bond are coplanar with an orientation perpendicular to the substituents on the alkene carbons, the four atoms bonded to the two carbons of the alkene must be coplanar"
Can anyone elaborate? I don't quite understand why the orbitals being perpendicular makes the substituents coplanar?
