Isoms gathered on the porch every summer to share stories.

During the analysis, we discovered that the sample contained an isomer that exhibited markedly different reactivity despite sharing the same molecular formula.

The chemist explained how isomers can have identical formulas but different properties.

Isom greeted each guest personally as they arrived at the gallery opening.

The exo-isomer of the bridged bicyclic compound was more reactive in Diels–Alder reactions because its substituent is positioned farthest from the longest bridge.

The synthesized endo-isomer exhibited higher stability because the substituent was positioned closest to the longest bridge in the bicyclic scaffold.

In the lab, we separated several structural isomers using gas chromatography.

The pharmaceutical chemist analyzed the mixture and identified four positional isomers.

The chemist explained how optical isomers can have identical physical properties yet interact differently with polarized light and biological receptors.

The metastable isomer persisted for hours before decaying to the ground state, allowing researchers to study its spin-dependent transition.
