An organic compound X having molecular formula C₅H₁₀O yields phenyl hydrazone and gives negative response to the iodoform test and tollen test. It produces n -pentane on reduction X could be

pentanal

2-pentanone

3-pentanone

n -amyl alcohol

Solution

3-pentanone

since the compound X yields phenyl hydrazone and gives a negative response to the iodoform test and tollen 's test. it must contain a C=O group but is neither a methyl ketone nor an aldehyde. having molecular formula C₅H₁₀O
