1) A substance C4H10O yields on oxidation a compound, C4H8O which gives an oxime and a positive iodoform test. The original substance on treatment with conc. H2SO4 gives C4H8. The structure of the compound is A) CH3CH2CH2CH2OH B) CH3CHOHCH2CH3 C) (CH3)3COH D) CH3CH2−O−CH2CH3 Answer: Option BExplanation: Thus C4H8O should be CH3COCH2CH3, hence C4H10O should be CH3CHOHCH2CH3
