Compound 'A' `C_(5)H_(10)O` forms a phenyl hydrazone and gives a negative Tollen's reagent test and iodoform test. On reduction with Zn-Hg/HCl, compound A gives n-Pentane. The compound 'A' is

A

`CH_(3)COCH_(2)CH_(2)CH_(3)`

B

`CH_(3)CH_(2)COCH_(2)CH_(3)`

C

`CH_(3)CH_(2)CH_(2)CH_(2)CHO`

D

`CH_(3)COCH(CH_(3))_(2)`

Text Solution
