Question

$\text{SO}_{2}+\text{NO+H}_{2}\text{O} \rightarrow \text{X+} \, \text{a} \, \text{dibasic} \, \text{acid}$
$\text{X} \, \overset{\text{NaNH}_{\text{2}}}{ \rightarrow }\text{Y}+\text{H}_{\text{2}}\text{O}$
In the above sequence, X and Y are respectively

• A. $NOHSO_{4},NaHSO_{4}$
• B. $NO_{2},NaNO_{2}$
• C. $N_{2}O,NaN_{3}$
• D. $N_{2}O,Na_{2}N$

Answer 1

Answer: (C)

Here X and Y are $N_{2}O,NaN_{3}$
$SO_{2}+2NO+H_{2}O \rightarrow \underset{\left(\right. X \left.\right)}{N_{2} O}+H_{2}SO_{4}$
$\underset{\left(\right. X \left.\right)}{N_{2} O}+NaNH_{2} \rightarrow \underset{\left(\right. Y \left.\right)}{N a N_{3}}+H_{2}O$
