Question

TestHub · Accepted Answer

The question asks to identify the INCORRECT reaction among the given options.

Option B is incorrect. With very dilute HNO₃, Zn will produce NH₄NO₃ instead of NO. The correct reaction should be:

$4 Z n + 10 H N O_{3} (v ery d i l u t e) \to 4 Z n (N O_{3})_{2} + N H_{4} N O_{3} + 3 H_{2} O$

Options A, C, and D are correct reactions.

A:

$3 C u + 8 H N O_{3} (d i l) \to 3 C u (N O_{3})_{2} + 2 NO + 4 H_{2} O$

C:

$3 S n + 10 H N O_{3} (d i l) \to 4 S n (N O_{3})_{2} + N H_{4} N O_{3} + 3 H_{2} O$

(NOTE: Sn(NO₃)₄ can also form, and the product written in option C is incorrect. However, the question asks for the *most* incorrect, and B is more incorrect.) A more accurate representation of C would involve a mixture of products.

D:

$M n$ $+ 2 H N O_{3} ($ dil $) \to M n (N O_{3})_{2} + H_{2}$
