Question

Assign the hybridization, shape and magnetic moment of $K_3\left[Cu{\left(CN\right)}_4\right]$.

• A. $s{p}^3$, tetrahedral , 1.73 B.M.
• B. $ds{p}^2$, square planar, 1.73 B.M.
• C. $s{p}^3$, tetrahedral, diamagnetic
• D. $ds{p}^2$, square planar, 2.44 B.M.

Answer 1

The correct option is C $s{p}^3$, tetrahedral, diamagnetic

In $K_3\left[Cu{\left(CN\right)}_4\right]:$,
$C{u}^{+},d^{10}$ configuration with zero unpaired electron so diamagnetic.
Also, its connected with four ligands so $s{p}^3$ hybridization with tetrahedral structure.
