Question

Consider the following reaction sequence of alkene. \[ \text{CH}_3\text{CH} = \text{CH}_3 \xrightarrow{\text{O}_3} A \xrightarrow{\text{H}_2\text{O}} B \] What is the product B?

• A. CH\(_3\)CH\(_2\)COCH\(_3\)
• B. CH\(_3\)COCH\(_2\)
• C. CH\(_3\)CHO
• D. CH\(_3\)CH\(_2\)CHO

Hint:

Ozonolysis of alkenes produces carbonyl compounds, and further reactions with water can lead to aldehydes or ketones depending on the structure of the starting alkene.

Answer 1

The Correct Option is C

The reaction sequence involves the ozonolysis of the alkene.
The reaction with ozone (\( \text{O}_3 \)) splits the alkene to form two carbonyl compounds.
The subsequent reaction with water reduces the intermediate product, leading to the formation of an aldehyde (CH\(_3\)CHO).

Thus, the correct answer is (c).
