Question

One mole of an organic compound 'A' with the formula $C_4{H}_{10}O$ reacts completely with excess of hot conc. HI to form X and Y. 'X' and 'Y' respond to wurtz reaction. The compound 'A' is____________

• A. methoxyethane
• B. propan-1-ol
• C. ethoxyethane
• D. propan-2-ol

Answer 1

The correct option is C ethoxyethane

Ether react with excess of hot conc. HI to form two mole alkyl iodide. Alkyl iodide in presence of sodium metal in dry ether give symmetrical alkane. wurtz reaction is best for the preparation of symmetrical alkane.
$C_2{H}_{5}O{C}_2{H}_5+HI\to C_2{H}_{5}I+C_2{H}_{5}I$
$C_2{H}_{5}I+2Na+C_2{H}_{5}I\to C_4{H}_{10}+2NaBr$
Hence correct option is (c).
