(b) Diethyl ether from sodium ethoxide.

OR

(ii) An organic compound [A] C₂H⁶O, on heating with cone. H₂SO₄ at 413K gives a neutral compound [B] C₄H₁₀O. Compound [B] on treatment with PCl₅ gives a product, which on subsequent treatment with KCN yields compound [C] C₃H₅N. Compound [C] on hydrolysis gives an acid [D] C₃H₆O₂. Identify the compounds [A],[B], [C] and [D].
