Respuesta :
The molecular shapes which have the most electron pairs shared around the central atom are pentagonal- bi-pyramidal shaped.
What are molecular shapes?
The molecular shapes are the shapes like linear, trigon planner, octahedral, tetrahedral, etc. which depend on the number of atoms and the lone pair and bond pair of atoms.
In pentagonal- bi-pyramidal shaped. a maximum number of electrons take part in the hybridization and can not have lone pairs to give repulsion to the bond pairs of the atoms.
Therefore, pentagonal- bi-pyramidal shapes are the molecular shapes that have the most electron pairs shared electrons around the central atom.
