Question

Anoin of cyclooctatetraene is less stable then cation of cyclooctatatetraene

Answer 1

 the preparation of uranocene, U(C8H8)2U(CX8HX8)X2. It has two cyclooctatetraenide anions, C8H82−CX8HX8X2−, as ligands, with a uranium atom between them.

It was mentioned that the neutral cyclooctatetraene molecule C8H8CX8HX8 is non aromatic and has a tub-shaped conformation, but the dianion C8H82−CX8HX8X2− is planar but aromatic. Wh

Answer 2

Hello mate,

Here is your answer,

If cyclooctatetraene were planar, it would be an antiaromatic compound according to Hückel's rule, because it has 8 π-electrons.

However, since its lowest energy conformation is non-planar, cyclooctatetraene can also be considered a non-aromatic compound.

The dianion has 10 π-electrons.

Thus, Anoin of cyclooctatetraene is less stable then cation of cyclooctatatetraene.

HOPE THIS HELPS UU :)

AND STAY BLESSED.
