Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Ozonolysis breaks double bond forming carbonyl compounds.
Step 1: Identify products.
• Propan-2-one (acetone)
• Formaldehyde
Step 2: Reconstruct alkene.
\[ (CH_3)_2C=CH_2 \]
Step 3: Identify compound.
Isobutene (2-methylpropene)
Step 1: Identify products.
• Propan-2-one (acetone)
• Formaldehyde
Step 2: Reconstruct alkene.
\[ (CH_3)_2C=CH_2 \]
Step 3: Identify compound.
Isobutene (2-methylpropene)
