How Many Isomers Does C4H9Br Have?

[nemzy]

The book says 4, but isn't there 5?

1) CH3-CH2-CH2-CH2-BR

2) CH3-CH2-CH-CH3
BR

3) CH3-CH-CH2-BR
CH3

4) CH3-CH2-CH-BR
CH3



CH3
5) CH3-C-CH3
BR



ugh..sorry i can't get the computer to place the atoms in the right place, but u guys get the picture

I think 2 and 4 are the same... Both can be read as 2-bromobutane, please look at them carefully, you'll see. I don't consider enantiomer formation, as there should be 2S-2-bromobutane and 2R-2-bromobutane, because they are not isomers, enantiomers, i.e., optical isomers.

About drawing formulae, I am not sure, but our moderator can show us how to arrange LateX to draw these formulae. It is possible, I know. If it isn't, it would be better for you to obtain some freeware chemical drawing software like ChemSketch or Isıs-Draw.

it have only two isomers

Thankyou!

THANKYOU!
:):!) your a real
this was a lot of help!
