Select incorrect about nontransition element (M) of 3d series :

Answer:

Solution:

The nontransition element (M) of the 3d series is Zinc (Zn).

Zinc reacts with both concentrated and dilute HNO₃.

With dilute HNO₃: $4 Z n + 10 H N O_{3} (d i l u t e) \to 4 Z n (N O_{3})_{2} + N_{2} O + 5 H_{2} O$

With concentrated HNO₃: $Z n + 4 H N O_{3} (co n c .) \to Z n (N O_{3})_{2} + 2 N O_{2} + 2 H_{2} O$

Therefore, option D is incorrect.
