Question

Which of the following compound is colored and paramagnetic?

• A. $ScC{l}_3$
• B. $TiC{l}_4$
• C. $CrC{l}_3$
• D. $CuCl$

Answer 1

Answer: (C)

$CrC{l}_3$

Electronic configuration of $S{c}^{+3}$ and $T{i}^{+4}$ is $\left[Ar\right]$.

Electronic configuration of $C{r}^{+3}$ is $\left[Ar\right]3d^3$.

Due to unpaired electrons it exhibit paramagnetic nature and due to empty d orbital it exhibit colour.

Option C is correct.
