1.	An organic compound X having molecular formular C_(4)H_(8)O gives orange-red ppt. with 2,4-DNP reagent. It doesnot reduce Tollen's but gives yellow ppt.Of iodoform on heating with NaOI. Compound X on reaction with LiAlH_(4) gives compound Y which undergoes dehydration reaction on heating with conc. H_(2)SO_(4) to form but-2-ene. Identify the compounds X and Y.
Answer» Solution :Compound `X=UNDERSET("Butan-2-one")(OVERSET(4)(C)H_(3)overset(3)(C)H_(2)overset(2)(C)Ooverset(1)(C)H_(3))` Compound `Y=CH_(3)-underset("Butan-2-ol")(CH_(2)-overset(OH)overset(\|)(CH))-CH_(3)` The REACTION can be explained as under:
