Question

An organic compound $${C_6}{H_{12}}\left( X \right)$$   on reduction gives $${C_6}{H_{14}}\left( Y \right).$$   $$X$$ on ozonolysis gives two aldehydes $${C_2}{H_4}O\left( {\text{I}} \right)$$   and $${C_4}{H_8}O\left( {{\text{II}}} \right).$$   Identify the compounds $$X, Y$$  and aldehydes $$\left( {\text{I}} \right)$$  and $$\left( {{\text{II}}} \right).$$

A. $$X = C{H_3}CH = CHC{H_2}C{H_2}C{H_3},$$       $$Y = C{H_3}{\left( {C{H_2}} \right)_4}C{H_3},$$     $$\left( {\text{I}} \right) = C{H_3}CHO,$$   $$\left( {{\text{II}}} \right) = C{H_3}{\left( {C{H_2}} \right)_2}CHO$$  
B. $$X = C{H_3}C{H_2}CH = CHC{H_2}C{H_3},$$       $$Y = C{H_3}{\left( {C{H_2}} \right)_4}C{H_3},$$     $$\left( {\text{I}} \right) = C{H_3}CHO,\left( {{\text{II}}} \right) = C{H_3}CHO$$
C. $$X = C{H_3}C{H_2}C{H_2}C{H_2}CH = C{H_2},$$       $$Y = C{H_3}{\left( {C{H_2}} \right)_3}C{H_3},$$     $$\left( {\text{I}} \right) = HCHO,\left( {{\text{II}}} \right) = C{H_3}{\left( {C{H_2}} \right)_2}CHO$$
D. \[X=C{{H}_{3}}C{{H}_{2}}\underset{\begin{smallmatrix} |\,\,\, \\ \,C{{H}_{3}} \end{smallmatrix}}{\mathop{-C=}}\,CH-C{{H}_{3}},\]       \[Y=C{{H}_{3}}{{\left( C{{H}_{2}} \right)}_{3}}C{{H}_{3}},\]     \[\left( \text{I} \right)=C{{H}_{3}}CHO,\left( \text{II} \right)=C{{H}_{3}}C{{H}_{2}}CHO\]
Answer :   $$X = C{H_3}CH = CHC{H_2}C{H_2}C{H_3},$$       $$Y = C{H_3}{\left( {C{H_2}} \right)_4}C{H_3},$$     $$\left( {\text{I}} \right) = C{H_3}CHO,$$   $$\left( {{\text{II}}} \right) = C{H_3}{\left( {C{H_2}} \right)_2}CHO$$
