Question

The coordination number of $N{i}^{2+}$ is 4.
$NiC{l}_2$ + KCN(excess) $\to$ A (Cyano complex)
$NiC{l}_2$ + conc HCl(excess) $\to$ B (Chloro complex)

The hybridization of A and B are :

• A. dsp${}^2$, sp${}^3$
• B. sp${}^3$, sp${}^3$
• C. dsp${}^2$, dsp${}^2$
• D. sp${}^3$d${}^2$, d${}^2$sp${}^3$

Answer 1

The correct option is A dsp${}^2$, sp${}^3$

$K_2\left[Ni\right(CN{)}_4]:ds{p}^2$-hybridization
$K_2\left[NiC{l}_4\right]:s{p}^3$-hybridization
