Interpretation:
The type of isomerism that could be exhibited by the given formulae and an example that illustrates the specific type of isomerism has to be stated.
Concept introduction:
Organic compounds which have similar chemical formula but different structures, i.e., the atoms are in a different spatial arrangement, they are known as structural isomers. Cis and Trans isomers are also structural or geometrical isomers.
