An alkene on ozonolysis gives methanal as one of the products. Its structure is:

1. CH₂ = CH₂ → CH₃
2. CH₂ = CH → CH₂
3. CH₂CH₂CH₃
4. CH₂ = CH₂

Correct answer: CH₂ = CH₂

Solution

Ozonolysis of ethene (CH₂=CH₂) produces two molecules of methanal (HCHO). This is because the double bond breaks, and each carbon forms a bond with oxygen, resulting in methanal.
