Consider following compounds and decide as to which of the following statements are true ?

(1) (II) gives no reaction with Na metal, however, 1 mole of (IV) on reaction with Na metal will liberate 22.4 litres of H2 gas at STP

(2) (I) will give brisk effervescence on addition of NaHCO3 but will not bring any change in the colour of Br2 water

(3) (III) Iiberates H2 gas with Na metal, gives white precipitate with Tollen's reagent but does not respond towards lucas reagent or 2, 4–DNP test.

(4) (IV) gives turbidity with anhydrous ZnCI2
