1.	Compound (A) of molecular formula C_(3)H_(6)O liberates hydrogen with sodium metal. (A) with P//I_(2) gives (B). Compound (B) on treatment with silveer nitrite gives ( C) which gives blue color with nitrous acid. Identify (A), (B), ( C) and explain the reactions.
Answer» Solution :(i) Compound (A) molecular formula `C_(3)H_(8)O` is isopropyl alcohol, `CH_(3)-underset(OH)underset(\|)(CH)-CH_(3)` (ii) Isopropyl alcohol REACTS with `P//I_(2)` to GIVE Isopropyl Iodide (B). `CH_(3)-underset((A))underset(OH)underset(\|)(CH-CH_(3)) overset(P)underset(I_(2)) to underset(P) to underset((B))(AgNO_(2))` (iii) (B) reacts with `AgNO_(2)` to form (C), (C) in turn reacts with nitrous acid to form pseudonitrol (blue colour).
