A) 1-butene
B) 2-butene
C) 150-butene
D) 2-butyne
Correct Answer: C
Solution :
Acetone is obtained by the ozonolysis of iso- butene, while 1-butene and 2-butene on ozonolysis give aldehyde and 2-butyne gives diketone. \[\underset{iso-butene}{\mathop{\overset{C{{H}_{3}}}{\mathop{\overset{|}{\mathop{C{{H}_{3}}-C=C{{H}_{2}}}}\,}}\,}}\,\xrightarrow[Zn/{{H}_{2}}{{O}_{2}}]{{{O}_{3}}}\underset{acetone}{\mathop{\overset{C{{H}_{3}}}{\mathop{\overset{|}{\mathop{C{{H}_{3}}-C=O}}\,}}\,}}\,\]\[+\underset{formaldehyde}{\mathop{HCHO}}\,\]
