Answer:
The Jahn-Teller effect is a geometric distortion of a non-linear molecular system that reduces its symmetry and energy. This distortion is typically observed among octahedral complexes where the two axial bonds can be shorter or longer than those of the equatorial bonds.

Explanation:
Cr(H
2
O)
6
]
2+
shows the strongest distortion from the regular octahedral structure.
The central Cr atom in +2 oxidation state has 3d
4
outer electronic configuration.
It has degenerate electronic states occupying the eg orbital set and tend to show stronger Jahn-Teller effects.
