Question

please explain

John teller distortion ?
and trans effect ??

Answer 1

JAHN TELLER DISTORTION : EXPLANTION

* In the electronically degenerate state, the orbitals are said to be asymmetrically occupied and get more energy. Therefore the system tries to get rid of this extra energy by lowering the overall symmetry of the molecule i.e., undergoing distortion, which is otherwise known as Jahn Teller distortion.

TRANS EFFECT

The trans effect is the ability of a ligand to influence the substitution of another ligand which is positioned trans to it in any square planar complexed.

_________________________________

JAHN TELLER DISTORION

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

TRANS EFFECT

✏✏The trans effect is the labilization of ligands that are trans to certain other ligands, which can thus be regarded as trans-directing ligands. It is attributed to electronic effects and it is most notable in square planar complexes, although it can also be observed for octahedral complexes...
