For the following molecules : PCl(5), ...

For the following molecules :
`PCl_(5), BrF_(3), IC l_(2)^(-), XeF_(5)^(-),NO_(3)^(-),XeO_(2)F_(2),PCl_(4)^(+),CH_(3)^(+)`
Calculate the value of `(a+b)/(c )`
a = Number of species having `sp^(3)` d-hybridisation
b= Number of species which are planar
c= Number of species which are non-planar

Text Solution

Verified by Experts

The correct Answer is:
3
`PCl_(5) to sp^(3)d`, non-planar
`BrF_(3) to sp^(3)d`, bent, T-shape. Planar
`Icl_(2)^(-) to sp^(3)d`, linear planar
`XeF_(5)^(-) to sp^(3)d^(3)`, pentagonal planar
`NO_(3)^(-) to sp^(2)`, planar
`XeO_(2)F_(2) to sp^(3)d,` sec-saw, non-planar
`PCl_(4)^(+) to sp^(3)`, tetrahedral, non-planar
`CH_(3)^(+) to sp^(2)`, Trigonal planar
a=4, b=5, c=3
so, `(a+b)/c =3`
