Which compound would give 3-methyl-6-oxoheptanal upon ozonolysis ?
Show Hint
The Correct Option is B
Approach Solution - 1
Approach Solution -2
The problem requires determining which compound gives 3-methyl-6-oxoheptanal upon undergoing ozonolysis. Ozonolysis is a reaction where an alkene is cleaved by ozone (O3) to form two carbonyl compounds. Let us analyze the options to find the correct precursor compound:
- Understand the structure of the desired product, 3-methyl-6-oxoheptanal. This compound is an aldehyde with the following structure:
CH3-CH2-CH(CH3)-CH2-CH2-C(=O)-CH3 - Identify possible alkenes that, when cleaved by ozonolysis, result in two carbonyl fragments that resemble the desired product.
- For each option, assume cleavage at the double bond and determine the resulting products:
- Option A:This compound does not provide the correct aldehyde and ketone upon ozonolysis.
- Option B:Ozonolysis of this compound would give the following fragments:
- CH3-CH2-CH2-C(=O)-H
- CH3-C(=O)-CH2-CH(CH3
- Option C:This compound does not yield the correct ozonolysis fragments to make 3-methyl-6-oxoheptanal.
- Option D:The ozonolysis products of this compound do not match the required aldehyde and ketone.
Based on the analysis, Option B is the compound that, upon ozonolysis, forms 3-methyl-6-Ketoheptanal.
