Question

Match the column:
$\begin{array}{cc}\text{Column-I}& \text{Column-II}\\ \text{(1) Chromite ore}& \text{(P) ZnS}\\ \text{(2) Malachite ore}& \text{(Q)}FeO.C{r}_2{O}_3\\ \text{(3) Cryolite}& \text{(R)}CuC{O}_3.Cu(OH{)}_2\\ \text{(4)}ZincBlende& \text{(S)}N{a}_{3}Al{F}_6\end{array}$

• A. 1 - P, 2 - Q, 3 - R, 4 - S
• B. 1 - Q, 2 - R, 3 - S, 4 - P
• C. 1 - S, 2 - P, 3 - R, 4 - Q
• D. 1 - Q, 2 - S, 3 - P, 4 - R

Answer 1

The correct option is B 1 - Q, 2 - R, 3 - S, 4 - P

(1) Chromite ore: $FeO.C{r}_2{O}_3$
(2) Malachite: $CuC{O}_3.Cu(OH{)}_2$
(3) Cryolite: $N{a}_{3}Al{F}_6$
(4) Zinc blende: $ZnS$
