Question

How many structural isomers does the molecule below have? The molecule below count as one isomer.

Answer 1

The molecular formula of this molecule is, `C_4H_9Br` and it has no degrees of unsaturation.

This means no cyclic or alke/ynes will be constitutional isomers of this molecule.

Since you never specified the stereochemistry of this molecule, there would likely be only three (stable) constitutional isomers, including yours,
