Aqueous sodium bicarbonate was used to wash the crude nbutyl bromide. (a) What was the purpose of this wash? Give equations. (b) Why would it be undesirable to wash the crude halide with aqueous sodium hydroxide?
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 3 CH 2 ONa. Sodium ethoxide is known as an alkoxide. If the solution is evaporated carefully to dryness, the sodium ethoxide is left as a white solid.
