These halide ion compounds exist in different forms in nature as solutions, precipitates and solids. The reaction gives the best results with primary halides. 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. Ethanol isn't as polar as water, because a large part of it is the non-polar hydrocarbon chain. The yield was 89.7% as measured by 1H NMR using 1,4-dioxane as an internal standard.
