# The gas given off when ethanol reacts with sodium is

### Question

The gas given off when ethanol reacts with sodium is

### Options

A) Carbon(IV)oxide

B) Hydrogen

C) Methane

D) Oxygen

### Explanation:

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.

2CH$$_3$$CH$$_2$$OH + 2Na $$\rightarrow$$ 2CH$$_3$$CH$$_2$$ONa + H$$_2$$
