General Principles and processes of Isolation of Elements
hard
Match the refining methods (Column $I$) with metals (Column $II$).
| Column $I$ (Refining methods) | Column $II$ (Metals) |
| $(I)$ Liquation | $(a)$ $Zr$ |
| $(II)$ zone Refining | $(b)$ $Ni$ |
| $(III)$ Mond process | $(c)$ $Sn$ |
| $(IV)$ Van Arkel Method | $(d)$ $Ga$ |
A
$(I) -(b); (II) -(c); (III) -(d); (IV) -(a)$
B
$(I) -(b); (II) -(d); (III) -(a); (IV) -(c)$
C
$(I) -(c); (II) -(a); (III) -(b); (IV) -(d)$
D
$(I) -(c); (II) -(d); (III) -(b); (IV) -(a)$
(JEE MAIN-2019)
Solution
Liquation is used for $Sn$. Zone refining is used for $Ga$. Mond's process is used for $Ni$. Van arkel process is used for $Zr$.
