Question

An alkene of molecular formula \( C_9H_{18} \) on ozonolysis gives \( 2 \)-dimethylpropanal and \( 2 \)-butanone, then the alkene is:

• A. 2,2,4-trimethyl-3-hexene
• B. 2,2,6-trimethyl-3-hexene
• C. 2,3,4-trimethyl-2-hexene
• D. 2,2-dimethyl-2-heptene

Hint:

Ozonolysis cleaves carbon-carbon double bonds to form carbonyl-containing products such as aldehydes and ketones.

Answer 1

The Correct Option is A

The ozonolysis of the alkene breaks it into aldehydes and ketones. Based on the product distribution, the alkene with the given formula is \( 2,2,4 \)-trimethyl-3-hexene.
Final Answer: \[ \boxed{2,2,4 \text{-trimethyl-3-hexene}} \]
