                  Which alkene on ozonolysis gives and ?                                                

A)                                

B)                 \[C{{H}_{3}}C{{H}_{2}}CH=CHC{{H}_{2}}C{{H}_{3}}\]

C)                 \[C{{H}_{3}}C{{H}_{2}}CH=CHC{{H}_{3}}\]                            

D)                 \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  C{{H}_{3}} \end{smallmatrix}}{\mathop{C}}\,=CHC{{H}_{3}}\]

Correct Answer: A

Solution :

                When \[{{O}_{3}}\] reacts with alkene, it forms ozonide, which on reaction with Zn and acid of \[{{H}_{2}}/Ni\] gives aldehydes and/or ketones. These products helps in locating the position of a double bond as ?
