Question:
Which of the following nitroalkane does not react with nitrous acid?
Which of the following nitroalkane does not react with nitrous acid?
Show Hint
Reaction with nitrous acid is a test to distinguish primary, secondary, and tertiary nitroalkanes.
Updated On: Feb 11, 2026
- 2-Methyl-2-nitropropane
- 2-Nitropropane
- Nitroethane
- 1-Nitropropane
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding reaction with nitrous acid.
Primary and secondary nitroalkanes react with nitrous acid due to presence of an \(\alpha\)-hydrogen atom.
Step 2: Analyzing tertiary nitroalkanes.
Tertiary nitroalkanes do not have any \(\alpha\)-hydrogen atoms and therefore do not react with nitrous acid.
Step 3: Identifying the compound.
2-Methyl-2-nitropropane is a tertiary nitroalkane and lacks \(\alpha\)-hydrogen atoms.
Step 4: Conclusion.
Hence, 2-methyl-2-nitropropane does not react with nitrous acid.
Primary and secondary nitroalkanes react with nitrous acid due to presence of an \(\alpha\)-hydrogen atom.
Step 2: Analyzing tertiary nitroalkanes.
Tertiary nitroalkanes do not have any \(\alpha\)-hydrogen atoms and therefore do not react with nitrous acid.
Step 3: Identifying the compound.
2-Methyl-2-nitropropane is a tertiary nitroalkane and lacks \(\alpha\)-hydrogen atoms.
Step 4: Conclusion.
Hence, 2-methyl-2-nitropropane does not react with nitrous acid.
