Question
Which of the following structural formulas represents an isomer of the compound that has the structural formula represented above?
▶️Answer/Explanation
Ans:B
An isomer has the same chemical formula, but a different structural formula. Remember, these are not flat structures and since all singly bonded, the carbons can rotate around the central axis of the chain. In other words, if the Br is attached to either end of a 3-C chain, it is the same structure as presented and NOT an isomer. (E) is a 4-C chain and (A), (C), and (D) all have Br attached to an end carbon. Only answer (B) is an isomer.
