Vedclass · Answer

(B) The molecule $ML_x$ has $7$ electron pairs in the valence shell of the central atom $M$.For the molecule to be planar with $7$ electron pairs,the geometry must be pentagonal bipyramidal,where $5$ bond pairs are in the equatorial plane and $2$ lone pairs occupy the axial positions (above and below the plane).This arrangement minimizes electronic repulsion.Since there are $5$ bond pairs,the number of ligands $x$ is $5$.

The molecule $ML_x$ is planar with $7$ pairs of electrons around $M$ in the valence shell. The value of $x$ is
