- \(\text{NH}_2\)
- \(\text{C}_2\text{H}_5\text{NH}_2\)
- \(\text{C}_2\text{H}_5\text{N}\text{H}_2\)
- \(\text{C}_2\text{H}_5\text{N}_3\)
Show Solution
The Correct Option is A
Solution and Explanation
Primary amines (\( \text{NH}_2 \)) yield an alcohol when reacted with nitrous acid (HNO₂). This process involves diazotization followed by hydrolysis. Secondary and tertiary amines exhibit different reactivity patterns with nitrous acid.
