An organic compound having molecular, C_(4)H_(10)Odoes not react with metallic sodium. On heating this compound with excess of constant boiling HI (density 1.7 g/mL) in a sealed tube, yields ethyl iodide as the only organic compound. What is the organic compound?

Answer»

SOLUTION :(i) Since the compound with M.F. `C_(4)H_(10)O` does not REACT with metallic solution, it cannot be an alcohol
(ii) Since on heating with excess of HI in a sealed TUBE, it gives ETHYL iodide as the only organic compound, therefore, it must be diethyl ether.
`underset("Diethyl ether")(CH_(3)CH_(2)-O-CH_(2)CH_(3))+2HI overset(Delta)to underset("Ethyl iodide")(2CH_(3)CH_(2)-I)+H_(2)O`
