Constitutional Isomers

Postby Steph S 2F » Sat Feb 27, 2016 1:16 pm

For constitutional isomers of a molecule, can we attach carbons in any way as long as we don't attach one to the ends of a carbon chain?

I am a little confused by the question. You can attach them in any way, as long as the overall formula is still the same but the connectivity is different.

When finding constitutional isomers, if you start with a typical straight chain of carbons, attaching another carbon to the end of the chain will not give you a unique structure but just the exact same structure. Therefore, attaching it towards the middle of the chain or other spots will usually give you a unique shape. One tip is always to check the longest carbon chain, see what branches off of it, and compare it to other structures with the same chain length.

Hope that helps!
