Describe how you could form ethyl ethanoate using only ethanol as the starting material. Include all relevant reagents and conditions.

To perform the esterification, we are going to need to react a carboxylic acid with an alcohol (in this case). We already have the correct alcohol: ethanol. Therefore to get ethanoic acid we must oxidise ...

Explain the difference in reactivity between benzene and phenol with bromine?

Phenol reacts with bromine at room temperature with no catalyst as the hydroxyl group activates the ring by donating a pi electron. This donated electron increases the electron density of the ring hence a...

What are the properties of ionic compounds?

As you may know, ionic compounds are composed of electrostatic forces of attraction between oppositely charged ions. This means that there are no free moving ions in the compound, as they have all been bo...

A buffer solution was formed by mixing 20.0 cm^3 of sodium hydroxide solution of concentration 0.100 mol dm^–3 with 25.0 cm^3 of ethanoic acid of concentration 0.150 mol dm^–3. CH3COOH + NaOH---CH3COONa + H2O Calculate the pH of this buffer solution.

Ka for ethanoic acid = 1.74 × 10–5 mol dm–3 also given in question. moles = concentration x volume / 1000Ka = [H+] [A-]/[HA]pH = -log [H+]
initial moles:NaOH: 20x0.1/1000 = 0.002molCH...
