Guida verificata passo dopo passo1
Understand that constitutional (structural) isomers are compounds that have the same molecular formula but different connectivity of atoms.
Identify the molecular formulas of each pair of compounds given and check if they are the same.
For pairs with the same molecular formula, analyze their structures to see if the connectivity of atoms differs (e.g., straight chain vs branched chain).
For example, compare n-pentane and 2-methylbutane: both have the formula \(C\_5H\_{12}\) but differ in the arrangement of carbon atoms, making them constitutional isomers.
Contrast pairs like ethane (\(C\_2H\_6\)) and ethene (\(C\_2H\_4\)), which have different molecular formulas and thus are not isomers.
