According to hybridisation theory, the % s-character in `sp, sp^(2) and sp^(3)` hybrid orbitals is 50, 33.3 and 25 respectively, but this is not true for all the species. When `theta` is the bond angle between equivalent hybrid orbitals then % s and p-character in hybrid orbitals (when only s and p-orbitals are involved in hybridisation) can be calculated by the following formula :
`costheta=(S)/(S-1)=(P-1)/(P)`
Q. Correct order of `P-P` bond length in the following compound is :

Options

A. `P_(2)F_(4)ltP_(2)(CH_(3))_(4)ltP_(2)(CF_(3))_(4)ltP_(2)H_(4)`
B. `P_(2)F_(4)ltP_(2)(CF_(3))_(4)ltP_(2)(CH_(3))_(4)ltP_(2)H_(4)`
C. `P_(2)F_(4)ltP_(2)H_(4)ltP_(2)(CH_(3))_(4)ltP_(2)(CF_(3))_(4)`
D. `P_(2)F_(4)ltP_(2)(CH_(3))_(4)ltP_(2)H_(4)ltP_(2)(CF_(3))_(4)`
