Ethanol in presence of sodium wire yields
Answers
Answer:
f a small piece of sodium is dropped into ethanol, it reacts steadily to give off bubbles of hydrogen gas and leaves a colorless solution of sodium ethoxide: CH3CH2ONa . The anion component is an alkoxide.
2CH3CH2OH(l)+2Na(s)→2CH3CH2O−(aq)+2Na+(aq)+H2(g)(1)
If the solution is evaporated carefully to dryness, then sodium ethoxide ( CH3CH2ONa ) is left behind as a white solid. Although initially this appears as something new and complicated, in fact, it is exactly the same (apart from being a more gentle reaction) as the reaction between sodium and water - something you have probably known about for years.
2H2O(l)+2Na(s)→2OH−(aq)+2Na+(aq)+H2(g)(2)
If the solution is evaporated carefully to dryness, then the sodium hydroxide ( NaOH ) is left behind as a white solid.
We normally, of course, write the sodium hydroxide formed as NaOH rather than HONa - but that's the only difference. Sodium ethoxide is just like sodium hydroxide, except that the hydrogen has been replaced by an ethyl group. Sodium hydroxide contains OH− ions; sodium ethoxide contains CH3CH2O− ions.
