What happens when a small piece of sodium is dropped into ethanol

On dropping a small piece of sodium in a test tube containing carbon compound 'X' with molecular formula C2H6O , a brisk effervescence is observed and a gas and Y is produced. On bringing a burning splinter at the mouth of the test tube the gas evolved burns with a pop sound. Identify 'X' and 'Y' . Also write the chemical equation for the reaction. Write the name and structure of the product formed, when you heat 'X' with excess conc. sulphuric acid?

The reaction mechanism between ethanol and sodium is as follows: • The formation of hydrogen gas bubbles and Sodium ethoxide is formed with a colorless solution. • 2 CH 3 CH 2 OH ( l ) Ethanol + 2 Na ( s Sodium ) → 2 CH 3 CH 2 ONa ( l ) Sodium ethoxide + H 2 ( g ) Hydrogen • Sodium ethoxide contains a cation ( Na + ) and an anion ( CH 3 CH 2 O - ). • The anion compound is known as ethoxide.

Table of Contents • • • • What happens when a sodium chloride is added to the ethanol solution? If 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. Does NaCl react with ethanol? If solvation energy of solvent is greater than the lattice energy of ionic solid then the ionic solid dissolves in the given solvent. Thus NaCl is sparingly soluble in ethanol but highly soluble in water. Why is NaCl soluble in ethanol? The strongest forces in ethanol are the dipole-dipole forces we call hydrogen bonds. The strongest forces in a solution of NaCl in ethanol will be ion-dipole forces. Just as they do in water, the Cl- ions are attracted to the partially positive H atoms in the OH groups of ethanol.

When any ethanol is dumped onto a tiny piece of sodium, it reacts slowly to produce hydrogen gas bubbles and leaves a colourless sodium ethoxide solution, CH3CH2ONa. Alkoxide is known as sodium ethoxide. What happens when you mix alcohol and salt? Adding salt to water/alcohol mixtures can separate them into layers. Even though water and alcohol mix well together, alcohol and salt do not. When salt is added to the solution, the salt dissolves in the water but not in the alcohol. Two layers are formed, with the alcohol layer on top. Does C2H...

alcohols and sodium REACTING ALCOHOLS WITH SODIUM This page describes the reaction between alcohols and metallic sodium, and takes a very brief look at the properties of the alkoxide which is formed. We will look at the reaction between sodium and ethanol as being typical, but you could substitute any other alcohol you wanted to - the reaction would be the same. The reaction between sodium and ethanol Details of the reaction If a small piece of sodium is dropped into some ethanol, it reacts steadily to give off bubbles of hydrogen gas and leaves a colourless solution of sodium ethoxide, CH 3CH 2ONa. Sodium ethoxide is known as an alkoxide. If the solution is evaporated carefully to dryness, the sodium ethoxide is left as a white solid. Although at first sight you might think this was 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. Compare the two: 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 CH 3CH 2O - ions. Note: The reason that the ethoxide formula is written with the oxygen on the right unlike the hydroxide ion is simply a matter of clarity. If you write it the other way around, it d...
