Question

An alkene having molecular formula \( C_8H_{12} \) on ozonolysis yields glyoxal and 2, 2-dimethyl butane-1, 4-dial. The structure of the alkene is:

• A. A
• B. B
• C. C
• D. D

Hint:

Ozonolysis of alkenes leads to cleavage of the double bond, forming carbonyl compounds as products.

Answer 1

The Correct Option is B

Step 1: Understand the reaction mechanism.
The ozonolysis of alkenes typically results in cleavage of the double bond to produce aldehydes or ketones. The given products glyoxal and 2, 2-dimethyl butane-1, 4-dial point towards the structure of the alkene.
Step 2: Conclusion.
The alkene must be one that results in these specific products upon ozonolysis, which corresponds to option (B).
Final Answer: \[ \boxed{B} \]
