Solution

The correct option is B 3
Steps for finding valency factor/n-factor:
1. Find the oxidation state (O.S.) of metal in reactant side.
2. Find the oxidation state of metal in product side.
3. Take the magnitude of difference of two oxidation state $| O . S ._{P r o d u c t} - O . S ._{R e a c t a n t} |$ for the valency factor

$(N H_{4} C l + N a N O_{2} \to N_{2} + H_{2} O + N a C l$
O.S. of N in reactant side
$\Rightarrow x + 1 \times (- 1) + 4 \times (+ 1) = 0$
$\Rightarrow x = - 3$

O.S. of N in product side
$\Rightarrow x = 0$ as nitrogen is present in natural state.

$valency factor = | O . S ._{P r o d u c t} - O . S ._{R e a c t a n t} |$
$valency factor = | 0 - (-) 3 |$
$valency factor = 3$

n-factor of $N H_{4} C l = number of N atom \times | O . S ._{P r o d u c t} - O . S ._{R e a c t a n t} | = 1 \times 3 = 3$
