Point group of dichlorospiroheptane
« on: October 23, 2017, 03:03:29 PM »
Hey guys,

I'm working on a problem that involves the point group of dichlorospiroheptane. I though it was a Cs or C1, but these are both wrong. I'm having trouble seeing any other symmetry operations, so I was just looking for some input. I attached a picture of the molecule below. Thanks

What symmetry operations do you see?

All i can see is an E operation and possibly a C2 but i'm not sure

I believe there's a C2 axis, but it's really hard to picture.

Here's a way: take the index fingers of your two hands and make an X with them right in front of your face so you are looking right where your fingers cross. Imagine the fingernails are the two chlorine atoms. Do you see it now?

Yes thats what i was thinking. So in that case it would be a C2 point group right?

Yes I would think so.
