Question

In the following sequence of reactions, the alkene gives the compound $B. B$ is $CH _{3}- CH = CH - CH _{3} \xrightarrow{ O _{3}} A \xrightarrow{ H _{2} O / Zn }B$

• A. $CH _{3} CH _{2} CHO$
• B. $CH _{3} CH _{3}$
• C. $CH _{3} CH _{2} COCH _{3}$
• D. $CH_{3}CHO$

Answer 1

Answer: (D)

$CH_{3}CHO$

Answer 2

$\underset{2-\text{butene}}{CH _{3}- CH = CH - CH _{3} }\xrightarrow [\text{ozonolysis}]{O_3}$ Hence, the given alkene on ozonolysis gives only acetaldehyde.
