Branched-chain isomer?
Attachment not found
I am unsure how to approach this question. Can somebody help please?
I'm assuming you know the what a branched chain and an optical isomer are.
All you have to do is re arrange some atoms/groups of atoms in the molecule to form another molecule that achieves both outcomes.
As per MS: label all the carbons 1-5 starting from left going to right.
1st molecule:
*take a hydrogen off at C4 (leaves CH free radical at Carbon 4 = C4)
*methyl group off C1 (this will leave with CH2 free radical at C2)
now place the H on C1, and CH3 on C4.
2nd molecule:
* take off Br at C3
* take off CH3 at C1
swap the groups for each other

Thanks a lot!
So it's just a bit of trial and error for this question, right?
Also, for the last one in the ms, how can Br form 2 bonds?
