In the following sequence of reactions, the alkene affords the compound 'B' \[C{{H}_{3}}CH=CHC{{H}_{3}}\xrightarrow{{{O}_{3}}}A\,\xrightarrow[Zn]{{{H}_{2}}O}\,B\]. The compound B is       AIEEE  Solved  Paper-2007

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

B) \[C{{H}_{3}}CHO\]          

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

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

Correct Answer: B

Solution :

\[C{{H}_{3}}-CH=CH-C{{H}_{3}}\xrightarrow{{{O}_{3}}}\]                                                                                               \[\xrightarrow[\Delta ]{Zn/{{H}_{2}}O}2C{{H}_{3}}CHO+{{H}_{2}}O+ZnO\]
