- $\ce{NaNH2 }$
- $\ce{NH2NH2 }$
- $\ce{ N_2}$
- $\ce{NH4Cl }$

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Excess of ammonia $\left( NH _{3}\right)$ when reacts with sodium hypochlorite solution (NaOCl) in presence of glue or gelatin gives hydrazine $\left( NH _{2} \cdot NH _{2}\right)$ This process is known as Raschig process
$2 NH _{3}+ NaOCl \to N _{2} H _{4}+ NaCl + H _{2} O$
Addition of gelatin or glue suppress the side reaction by complexing with the metal ions and yield of hydrazine is increased.
$2 NH _{3}+ NaOCl \to N _{2} H _{4}+ NaCl + H _{2} O$
Addition of gelatin or glue suppress the side reaction by complexing with the metal ions and yield of hydrazine is increased.

Concepts Used:
P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
