A highly viscous compound (X) on reacting with conc. HNO_(3) gives an inorganic ester (Z) which on detonation gives CO_(2), N_(2), O_(2) as gaseous products. With KMnO_(4) it gives a compound (Y) of the molecular formula C_(2)O_(4)H_(2) which can also be obtained from glycol using same reagent. The compound (X) is

1.	A highly viscous compound (X) on reacting with conc. HNO_(3) gives an inorganic ester (Z) which on detonation gives CO_(2), N_(2), O_(2) as gaseous products. With KMnO_(4) it gives a compound (Y) of the molecular formula C_(2)O_(4)H_(2) which can also be obtained from glycol using same reagent. The compound (X) is
Answer» Phenol Glycerol Glycollic acid None of the above Solution :Clearly compound (Y) is `{:(COOH),("\|"),(COOH):}` The reactions are `{:(CH_(2)_OH),("\|"),(CH-OH overset(Conc. HNO_(3))RARR underset((Z))underset("Glycerltrinitrate")(C_(3)H_(5)(ONO_(2))_(3))overset("Detonating")rarrCO_(2)+N_(2)+O_(2)+H_(2)O),("\|"),(underset((X))(CH_(2)-OH)):}`
