NEET 2022, Chemistry Q36: General Principles And Processes Of Isolation Of Elements

NEET2022Chemistry
Q.

Match List-I with List-II.

List-I (Ores)List-II (Composition)
(a)Haematite(i)FeO
(b)Magnetite(ii)ZnCO
(c)Calamine(iii)FeO
(d)Kaolinite(iv)[Al(OH)SiO]

Choose the correct answer from the options given below :

  1. A

    (a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)

  2. B

    (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)

  3. C

    (a)-(i), (b)-(iii), (c)-(ii), (d)-(iv)

  4. D

    (a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)

Solution

Recall the standard mineral compositions.

Haematite is FeO, so (a) maps to (iii).

Magnetite is FeO, so (b) maps to (i).

Calamine is ZnCO, so (c) maps to (ii).

Kaolinite is the aluminosilicate clay [Al(OH)SiO], so (d) maps to (iv).
