Definitions:

Geometric Isomers

Molecules with the same molecular formula and sequence of bonded atoms (constitution), but differing in the three-dimensional orientations of their atoms in space.

(E)-2-pentene

An alkene with the formula CH3CH=CHCH2CH3 where the two substituents on the double bond are on opposite sides, denoted by the (E) configuration.

(Z)-2-pentene

An alkene with the chemical formula C5H10, where the double bond between carbons 2 and 3 has the highest priority substituents on the same side, following the Cahn-Ingold-Prelog priority rules.

Stereoisomers

Compounds sharing identical molecular formulas and sequences of bonded atoms, yet varying in the spatial arrangement of their atoms.
