NEETChemistryAldehydes and Ketones
What determines whether aldehydes, ketones, or a mixture of both is produced in the ozonolysis method?
Options
- AThe temperature of the reaction
- BThe pressure of the reaction
- CThe substitution pattern of the alkene
- DThe choice of catalyst
Correct answer
C. The substitution pattern of the alkene
Step-by-step solution
In the ozonolysis of alkenes, ozone (O 3 ) is used to cleave the double bond, resulting in the formation of carbonyl compounds, which can be aldehydes or ketones. The specific product formed depends on the substitution pattern of the alkene. After ozonolysis, the reaction mixture is treated with reducing agents like zinc dust and water to convert any intermediate ozonides into aldehydes or ketones. The choice of aldehyde or ketone product is determined by the arrangement of substituents on the original alkene molec
