Question

Iodine trichloride exists as a dimer $I_{2}C{l}_6,$ in solid state. Let, X = number of $3c-4e^{-}$ bond, Y = maximum number of atoms in a plane and Z = number of $2c-2e^{-}$ bond present in this molecule.Then find $\left(\frac{X\times Y}{Z}\right)$

Answer 1

$I_{2}C{l}_6$ contain $2,(3c-4e^{-})$ bonds and $4,(2c-2e^{-})bonds$.
It is a planar dimer. So, all the atoms are in plane.
Thus, $X=2,Y=8andZ=4$.
Hence $\frac{X\times Y}{Z}=4$
