Compound `X` of molecular formula `C_(4)H_(6)` takes up one equivalent of hydrogen in presence of `Pt` to form another compound `Y` which on ozonolysis gives only ethanoic acid. The compound `X` can be

Options

A. `CH_(2)=CH-CH=CH_(2)`
B. `CH_(2)=C=CHCH_(3)`
C. `CH_(3)C-=C CH_(3)`
D. All the three

Answer

D

Explanation

Formation of only `CH_(3)COOH` by ozonolysis indicates that the compound `Y` should be `CH_(3)CH=CHCH_(3)` which can be formed by all the three given compounds.
`underset(X)(CH_(3)=CH-CH=CH_(2))overset(1H_(2) // Pt) rarr underset(Y)(CH_(3)-CH=CH-CH_(3))`
`underset(X)(CH_(3)C-= C CH_(3))overset(1H_(2) // Pt)rarr underset(Y)(CH_(3)CH= CH_(3)CH_(3))`
`underset(X)(CH_(2)=C=CHCH_(3))overset(1H_(2) // Pt)rarr`
`underset(Y)(CH_(3)CH=CHCH_(3))overset(O_(3))rarr 2CH_(3)COOH`
