The molecule MLx is planar with 7 pairs of electrons around M in the valence shell. The value of x
is 5.
Note: There will be 5 bond pairs of electrons and two lone pairs of electrons. The electron geometry will be pentagonal bipyramidal and molecular geometry will be planar. 5 Bond pairs of electrons will be in one plane and two lone pairs of electrons will be opposite to each other, one above the plane and other below the plane. This will minimize the electronic repulsion.

Explanation:
To determine the value of x in the molecule MLx, we need to analyze the electron arrangement around the central atom M.
1. Determine the electron arrangement:
The fact that the molecule is planar indicates that the electron arrangement around M is trigonal planar. This means that there are three electron pairs in the equatorial plane and one pair above and below this plane.
2. Count the electron pairs:
To determine x, we need to count the number of electron pairs around M. Each bond counts as one pair, and lone pairs count as well.
In this case, we are given that there are 7 pairs of electrons around M. Let's break it down:
- There are three bonds (3 pairs of electrons) in the equatorial plane.
- There is one lone pair above the equatorial plane.
- There is one lone pair below the equatorial plane.
So far, we have accounted for 5 pairs of electrons.
3. Determine the value of x:
Since we have already accounted for 5 pairs of electrons, the value of x must be 5.
Therefore, the correct answer is '5'.
