The atomicity of white Phosphorous is X and the the `P − P − P` bond angle in the molecule is Y .What are X and y?

The atomicity of white phosphorus is X and the P-P-P bond angle is Y . What are X and Y ?

Cl-P-Cl bond angles in PCl_5 molecule are

P - P - P bond angle in white phosphorous is

Atomicity of white or yellow phosphorus is 4 annd it is represented as P_(4) molecule Calculate the value of expresion (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.

In a P_(4) molecule, the P – P – P bond angle is :

Most of the polyatomic molecules except a few such as CO_(2) and CS_(2) are linear or angular with a bond angle generally somewhat greater than 90^(@) A bond angle is defined as the angle between the direction of two covalent bonds Since the atoms in molecules are in constant motion with respect to each other they are not expected to have a fixed value of bond angle Repulsion between non-bonded atoms alone does not provide an adequate explanation Hybridisation of bonding orbitals an adequate explanation Hybridisation of bonding orbitals also plays a very important role in detrmining the value of bond angle It has been observed that in hybridisation as the s-character of hybrid orbital increases the bond angle increases In P_(4) molecule phosphorous atoms are tetrahedrally arranged The angle P-P-P in the molecule is .

Compare x and y bond angle from the above given molecules.

Atoms in P_4 molecule of white phosphorus are arranged regularly in the followinf way :

The total number of 'p' electrons present in phosphorous atom is

White phosphorus occurs as discrete P_4 units , where P atom lie at the corners of a regular tetrahedron . The PPP bond angle is
