A substance `C_(5)H_(10)O` does not reduce Fehling's solution, forms a phenylhdrazone, shows the haloform reaction, and can be converted into n-pentane by strong reduction. The structure formula of the original substance is:

A compound has molecular formula C_(6)H_(12)O . It does not reduce Tollens or Fehling's reagent, but gives a crystalline derivative with 2,4-dinitro-phenyl hydrazine. With alkali and I_(2) , it gives yellow solid with a medicinal odour. Clemmensen reduction converts it to 2-methylpentane. The structure formula of the compound is most likely to be:

An organic compound 'X' having molecular formula C_(5)H_(10)O yield phenylhydrazone and gives negative response to the iodoform test and Tollens test . It produces n-pentane on reduction. 'X' could be
