Molecular Geometry
« on: December 02, 2006, 12:53:44 AM »
I think that the molecular geometry for the hydrocarbon butane (C4H10) at each of the carbons atoms is tetrahedral for both isomers. Am I correct?

For C2HClBrF, I ended with 9 isomers. Correct?

Can you draw out all 9 isomers?  I count only 3.

Would 1 and 6, 2 and 5, 3 and 4, 5 and 7, 4 and 8, 6 and 9 be isomers of each other? This would leave only 1, 2, and 3 be the only isomers?

I suppose Ygg missed the fact that is alkene, not alkane. But you are wrong too. For example: 6 & 9 are identical.

So, does that mean there are 6 isomers, the first 6?

But isn't 2 and 5 the same? 3 and 4 the same? 1 and 6 the same? This leaves the first 3 (1,2,3) to be the only isomers?

Not checking others: 3 & 4 are different. Double bond is flat and doesn't rotate.

I can't believe that I spaced out that double bonds do not rotate. This will definately help me! Thanks a lot!

Well, I went through it again and ended up with 6 isomers, the first 6.
