C3H6Br2
There are 4 structural isomers possible to draw... which I'd like to do :)
The carbon skeleton isn't of much importance here, as we only have three carbon atoms. The two halides, however, are a pain, I've found.
The linear sigma bonds may rotate around its axis, meaning that several seemingly different structures basically are identical. Also, we can rotate the entire molecule, so we can that way also acknowledge several seemingly different structures as identical.
1) 2,2.dibromopropane
2) 1,2-dibromopropane (Br at the end no bonded at the end of the carbon chain, but either "up" or "down", if you get my point)
Br
C - C - C
###Br
3) 1,3-dibromopropane (each Br bonded to the ends of the carbon chain)
4) 1,2-dibromopropane (Br-CH2-C(Br)H-CH3)
Are these the correct structural isomers? Am I thinking correctly, here? I'm guessing that being able to efficiently identify isomers is a matter of practice and getting a "trained" eye, so to speak. I organic chemistry, they're telling us it's important to develop good 3D interpretations of 2D representations. A molecular building set is on the way from Evil-Bay
I appreciate any help :) I'll try to be a member of this community, and help where I'm able, and not just a user.
