The structure of diamagnetic nickel complex , `` is :

Options

A. triagonal bipyramidal
B. tetrahedral
C. square planar
D. distorted octahedral

Answer

C

Explanation

Molar mass of AgCl = 143.5 g`mol^(-)`
No . Of moles of AgCl precipitated
= `(4.305 g) / (143.4 gmol^(-))` = 0.03 mol
0.01 mole of complex precipitates AgCl = 0.03 mol
1.0 mole of complex precipitates AgCl = 3 mol
This means that the complex provides three `Cl^(-)` ions in solution. `therefore` Formula of complex = `[Co(NH_(3))_(6)]Cl_(3)`
