Question

Compound a having molecular formula c4h10o is found.To be soluble in concentrated sulphuric acid . It does not react with sodium metal or potassium permanganatw . On heating excess of hi . It gives a single alkyl halide. Deduce the structure of compound a and explain ll the reaction

Answer 1

Explanation:

As metallic sodium does not react with an ether, furthermore, an ether on reacting with excess of boiling HI can produce alkyl halides, and here only one alkyl halide is formed, the groups present on either side of the O atom in a ether must be ethyl.

i) When ether reacts with sulphuric acid, it forms an alkene and H2O

C4H10O + H2SO4 → C4H8 + H2O

(ii) (C2H5)2O + Na → No reaction

(iii) (C2H5)2O + HI → C2H5I

The compound is Diethyl ether

The IUPAC name of the compound is : Ethoxyethane , (C2H5)2O
