• # question_answer A compound (X) on ozonolysis followed by reduction gives an aldehyde, ${{C}_{2}}{{H}_{4}}O$ and 2-butanone, compound (X) is A) 3-methylpentene-2 B) 3-methylpentene-3 C) 3-methylhexene-3 D) 3-ethylpentene-3

 According to the given data, $\operatorname{X}\xrightarrow[\left( ii \right)Zn/AcOH]{\left( i \right){{O}_{3}}}C\underset{\operatorname{Aldehyde}}{\mathop{_{2}{{H}_{4}}O+C{{H}_{3}}}}\,\underset{2-Butanone}{\mathop{C{{H}_{2}}}}\,\overset{\overset{\operatorname{O}}{\mathop{\parallel }}\,}{\mathop{C}}\,C{{H}_{3}}$ The formula of an aldehyde with molecular formula ${{\operatorname{C}}_{2}}{{H}_{4}}O$is ${{\operatorname{CH}}_{3}}CHO.$ The compound X is
