Consider the following three compounds (...

Consider the following three compounds `(i)AX_(2n)^(n-)`, (ii)`AX_(3n)` and (ii)`AX_(4n)^(n+)`, where central atom A is 15th group element and their maximum covalency is 3n. If total number of proton in surrounding atom X is n and value of n is one, then calculate value of `x^(3)+y^(2)+z^(2)` . (where x, y and z are total number of lone pair at central atom in compounds (i), (ii) and (iii) respectively.

Text Solution

Verified by Experts

The correct Answer is:
9
n=1, then X=H, A=N
(i) `NH_(2)^(-)`, (ii) `NH_(3)`, (iii) `NH_(4)^(+)`
lone pair x=2, y=1, z=0
`x^(3) + y^(2) + z = (2)^(3) + (1)^(2) + (0) =9`
