Question

Identify the following pairs of structures as structural isomers, cis-trans isomers, or the same molecule:

Short answer

Part(a) The structures are same molecules.

Part(b) The structures are structural isomers.

Step-by-step solution

Part(a) Step 1 : Given information

We need to classify the pairs of structures as structural isomers, cis-trans isomers, or the same molecule

Part(a) Step 2 : Simplify

We can clearly see from the structures that they are same molecule as both have same orientation as well as empirical formula.

Hence, the structures are same molecule.

Part(b) Step 1 : Given information

We need to classify the pairs of structures as structural isomers, cis-trans isomers, or the same molecule

Part(b) Step 2 : Simplify

We can see both structures have different number of substituents and position of double bond is also not same.

Hence the structures are structural isomers.
