Ozonolysis of 2-butene

Ozonolysis is a chemical reaction that involves the cleavage of an alkene or alkyne bond by ozone (O3). When 2-butene undergoes ozonolysis, it forms an ozonide intermediate, which can further undergo hydrolysis to produce different products.

Hydrolysis of the ozonide of 2-butene

The hydrolysis of the ozonide of 2-butene involves the reaction of the ozonide with water (H2O). This reaction leads to the formation of two products: ethanal (also known as acetaldehyde) and hydrogen peroxide (H2O2).

The ozonide of 2-butene can be represented as follows:

CH3CH=CHCH3 + O3 → CH3CH(OO)CH(OO)CHCH3

When this ozonide reacts with water, it undergoes hydrolysis to produce ethanal and hydrogen peroxide:

CH3CH(OO)CH(OO)CHCH3 + H2O → CH3CHO + H2O2

Explanation of the correct answer

The correct answer is option D: ethanal and hydrogen peroxide. This is because the hydrolysis of the ozonide of 2-butene results in the formation of ethanal (also known as acetaldehyde) and hydrogen peroxide as the products.

Other options explained

Option A: ethylene only - This is not the correct answer because the hydrolysis of the ozonide of 2-butene does not produce ethylene as a product.

Option B: acetaldehyde and formaldehyde - This is not the correct answer because the hydrolysis of the ozonide of 2-butene only produces ethanal (acetaldehyde) as a product, not formaldehyde.

Option C: propionaldehyde and ethyl alcohol - This is not the correct answer because the hydrolysis of the ozonide of 2-butene does not produce propionaldehyde or ethyl alcohol as products.

In summary, the hydrolysis of the ozonide of 2-butene produces ethanal (acetaldehyde) and hydrogen peroxide as the products.
