JEE Main 2025 Jan 23 Shift 2, Chemistry Q13: Introduction to Metallurgical Processes

JEE Main2025Jan 23, Shift 2Chemistry
Q.

Match List - I with List - II.

List - IList - II
(A) Bronze(I) Cu, Ni
(B) Brass(II) Fe, Cr, Ni, C
(C) UK silver coin(III) Cu, Zn
(D) Stainless Steel(IV) Cu, Sn

Choose the correct answer from the options given below :

  1. A

    (A)-(IV), (B)-(II), (C)-(III), (D)-(I)

  2. B

    (A)-(IV), (B)-(III), (C)-(I), (D)-(II)

  3. C

    (A)-(III), (B)-(I), (C)-(IV), (D)-(II)

  4. D

    (A)-(III), (B)-(IV), (C)-(II), (D)-(I)

Solution

Standard compositions of common alloys:

Bronze is a CuSn alloy. (A) (IV)

Brass is a CuZn alloy. (B) (III)

The cupronickel used in modern UK silver-coloured coins is essentially Cu with Ni. (C) (I)

Stainless steel is Fe alloyed with Cr, Ni and a small amount of C. (D) (II)
