Question:
The products obtained by the ozonolysis of 2-methylbut-1-ene are
The products obtained by the ozonolysis of 2-methylbut-1-ene are
Show Hint
In ozonolysis, split the \(C=C\) bond and convert both alkene carbons into carbonyl groups.
Updated On: Apr 29, 2026
- Propanone and ethanal
- Propanone and methanal
- Butanone and methanal
- Ethanal and propanal
- Butanone and methanol
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Ozonolysis cleaves the carbon-carbon double bond and converts each double-bonded carbon into a carbonyl compound.
Step 1: Write the alkene.
2-methylbut-1-ene is: \[ CH_2=C(CH_3)CH_2CH_3 \]
Step 2: Break the double bond.
The terminal \(CH_2\) carbon gives: \[ HCHO \] which is methanal.
Step 3: Identify the other product.
The substituted carbon gives: \[ CH_3COCH_2CH_3 \] which is butanone.
