Question

What is the result of ozonolysis of propene?

• A. Formation of acetone and formaldehyde
• B. Formation of acetic acid
• C. Formation of methanol and ethanol
• D. Formation of two aldehydes or ketones

Hint:

Ozonolysis cleaves double bonds and forms carbonyl compounds (aldehydes or ketones).

Answer 1

The Correct Option is D

Ozonolysis of propene results in the formation of two carbonyl compounds. These compounds are typically either aldehydes or ketones. Upon ozonolysis, if the compound shows a magnetic moment (\( \mu = 1.73 \, \text{BM} \)), it indicates the presence of unpaired electrons in the molecule, which is characteristic of a paramagnetic substance. The magnetic moment is related to the number of unpaired electrons by the formula: \[ \mu = \sqrt{n(n + 2)} \, \text{BM}, \] where \( n \) is the number of unpaired electrons. A magnetic moment of \( 1.73 \, \text{BM} \) suggests that the molecule has one unpaired electron, confirming its paramagnetic nature.
