Title: isomerism
Post by: orgo814 on June 04, 2012, 03:56:58 PM
Can anyone explain why CH2ClCHClCH3 and CH3CHClCH2Cl are considered the same compound instead of constitutional isomers? Isomers have the same molecular formula but different structural formulas...these look like different structural formulas to me. However, the book says they are not constitutional isomers...they are the same compound.

Draw the structures or build them and turn them around in 3D. They are the same molecule. One is written forward and one is written backwards. If you turn one of the molecule around, they are the same compound, they are imposable.
