Pi orbital structure

Postby Jessica Yang 1J » Mon Nov 20, 2017 2:58 pm

I know that in class Dr.Lavelle said that one pi bond means that the atoms are forced in place and any rotation would result in a breaking of the pi bonds. What would happen with two bi ponds? Someone mentioned that they could rotate but I don't understand how.

I don't think a triple bond can rotate since it also contains two pi bonds.

I am fairly sure that any type of molecule that is held together by pi bonds is unable to rotate and will create a rigid planar structure for that molecule. When there are two pi bonds in place, rotation will become irrelevant since the molecule is linear. What I'm getting at is that if you flip the entire molecule over then it will be the same exact thing. This may be what the person is talking about when they are saying that it rotates. So just know that sigma bonds can rotate and pi bonds make it so that the molecule does not rotate and you'll be good to go!
