Question

What is the type of magnetic behavior and geometry respectively in Cuproammonium sulphate (Atomic number of Cu = 29)?

Options

• Paramagnetic and square planar

• Paramagnetic and tetrahedral

• Diamagnetic and pyramidal

• Diamagnetic and tetrahedral

Answer 1

Paramagnetic and square planar

Explanation:

Cuproammonium sulphate - \[\ce{[Cu(NH3)4]SO4 . H2O}\]

[Cu(NH₃)₄]²⁺ → Oxidation state of Cu = +2

dsp² - Square planar, Paramagnetic - One unpaired electron.
