E) Structural isomers have the same composition,but the atoms are linked in different ways.

Question

Quizplus · Accepted Answer

Geometric isomers refer to molecules that have the same molecular formula and sequence of bonded atoms (constitution), but the molecules differ in the three-dimensional orientations of their atoms in space. This concept is distinct from chirality, where chiral molecules are mirror images of each other and cannot be superimposed. The term "chiral pairs" specifically refers to enantiomers, not geometric isomers.
