Atomicity of white or yellow phoshporus ...

Atomicity of white or yellow phoshporus is 4 and it is represented as `P_(4)` molecule.
calculate the value of expression `(X*Y)/Z` regarding this molecule.
Where: X: total number of vertex angles in `P_(4)` molecule.
Y: Total number of lone pairs in `P_(4) `molecule.
Z: total number of P-P bonds in `P_(4)` molecule.

Text Solution

Verified by Experts

The correct Answer is:
8
`x=12" "y=4" "z=6`

The value of `(x*y)/(2)=(12xx4)/(6)=8`
