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

A)  \[C{{H}_{3}}C{{H}_{2}}CHO~\] 

B)  \[C{{H}_{3}}\text{ }C{{H}_{3}}\]

C)  \[C{{H}_{3}}C{{H}_{2}}COC{{H}_{3}}\]

D)  \[C{{H}_{3}}CHO\]

Correct Answer: D

Solution :

                \[\underset{2-butene}{\mathop{C{{H}_{3}}-CH=CH-C{{H}_{3}}}}\,\xrightarrow[(Ozonolysis)]{{{O}_{3}}}\] Hence, the given alkene on ozonolysis gives only acetaldehyde.
