Question

An isomer of \(\mathrm{C_4H_8}\) is \(X\), which exhibits cis-trans isomerism. \(Y\) is the chain isomer of \(X\). Products formed on ozonolysis of \(Y\) are

• A. \(\mathrm{CH_3CHO + CH_3CHO}\)
• B. \(\mathrm{CH_3CH_2CHO + HCOOH}\)
• C. \(\mathrm{CH_3COCH_3 + HCHO}\)
• D. \(\mathrm{CH_3CH_2COOH + CO_2}\) \bigskip

Hint:

Ozonolysis cleaves the C=C bond to form carbonyl compounds.

• Terminal carbon (\(\mathrm{=CH_2}\)) gives formaldehyde (\(\mathrm{HCHO}\)).
• Internal substituted carbon generally gives an aldehyde or ketone.

Answer 1

The Correct Option is C

Step 1: X: C₄H₈ with cis-trans isomerism → but-2-ene. Y: chain isomer → 2-methylpropene. Ozonolysis of Y → acetone + formaldehyde.

Step 2: Write the final answer. \(\boxed{\mathrm{CH_3COCH_3 + HCHO}}\)
