Fusion of chromite ore $\left(FeC{r}_2{O}_4\right)$ with  $N{a}_{2}C{O}_3$ in the presence of $O_2$ gives X which on acidification with conc.$H_{2}S{O}_4$  gives Y. Both X and Y contain chromium ion. Correct statement(s) is/are:

Acidified solution of Y can convert  $S{n}^{2+}$ ion into  $S{n}^{4+}$ ion.

Both X and Y are colourful compound and colour of these compounds is due to ligand to metal charge transfer.

Both X and Y have   bond

Both X and Y are paramagnetic in nature.
