Question

The molecule mlx is planar with six pairs of electrons around m in the valence shell. According to vsepr theory the value of x is.

Answer 1

Answer : The value of 'x' is 4.

Explanation :

According to the question, there are six pair of electrons around the 'm'(central atom) in the valence shell. So, the compound should be $ml_6$ and the shape of the compound will be octahedral according to VSEPR theory.

But given molecule is planar and the octahedral molecular geometry are not planar.

For planar molecule, there should be four ligands around the central atom and two pair of electrons present as the lone pair.

So, the formula of the compound will be $ml_4$ and the shape of the compound will be square planar in which two lone pairs will be present on the top and bottom of the planar arrangement.The square planar geometry shown below.  

Therefore, the value of 'x' is 4.
