Which one of the following can produce hydrogen when treated with metallic sodium?
Updated On: Jul 28, 2022
- $ {{(C{{H}_{3}})}_{2}}NH $
- $ C{{H}_{3}}N{{H}_{2}} $
- $ {{C}_{6}}{{H}_{5}}N{{H}_{2}} $
- $ C{{H}_{3}}CON{{H}_{2}} $
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
$CH _{3} CONH _{2}$ on treatment with metallic sodium produce hydrogen.
$CH _{3} CONH _{2}+ Na \rightarrow CH _{3} CONH ^{-} Na ^{+}+\frac{1}{2} H _{2} \uparrow$

Preparation of Dihydrogen
Laboratory Preparation of Dihydrogen is given below:
- Reacting Zinc with Acid - One common way to produce or prepare dihydrogen gas in the lab is by reacting Zinc with a diluted acid.
\(Zn + H_2SO_4 → ZnSO_4 + H_2\)
\(Zn +HCl → ZnCl_2 + H_2\)
- Reacting Zinc with Alkaline - Zinc can also react with an aqueous alkali such as Sodium Hydroxide, The sodium and zinc will combine and produces dihydrogen as another product. The reaction is given as:
\(Zn + 2NaOH → Na_2ZnO_2 + H_2\)
- Commercial Preparation of Dihydrogen - The commercial preparation of hydrogen is a huge industry due to the high demand for hydrogen in the production of fertilizers and the oil-refining process.
