Show Answer
Answer:
Correct Answer: B
Solution:
Propene gives formaldehyde and acetaldehyde on ozonolysis.
$ CH_2=CH.CH_3\xrightarrow{O_3} $
$ \overset{\underset{\hat{\ }}{\mathop{O}}}{\mathop{\overset{O}{\mathop{\overset{|}{\mathop{C}}}}H_2-\overset{O}{\mathop{\overset{|}{\mathop{C}}}}}}H.CH_3- $
$ \underset{H_2O_2}{\mathop{\xrightarrow{Zn/H_2O}}}HCHO+CH_3CHO $
