Question

When ethanol reacts with sodium, which gas will produce?
A.Hydrogen
B.Oxygen
C.Sodium ethoxide
D.Carbon dioxide

Answer 1

The gas released in this chemical process will have a pop sound. It will be the colorless, odorless gas.
While attempting this question, we should note that it is regarding which gas is produced and not the main product.

Complete step by step answer:
When ethanol ($C{H_3}C{H_2}OH$) reacts with sodium ($Na$), a clear solution of sodium ethoxide is formed and hydrogen gas is released. This experiment can be done in the labs with care. We need a test tube, a test tube holder, sodium ($Na$) pellets dipped in kerosene and ethanol. The $Na$ pellets should be sliced with precaution because they may cause burns. We will take the test tube in a test tube holder and add ethanol, $C{H_3}C{H_2}OH$ into it. Then, we will add a freshly sliced pellet of $Na$ into the test tube and cover it from the top. The clear solution of sodium ethoxide ($C{H_3}C{H_2}{O^ - }N{a^ + }$) will be formed. A gas of hydrogen,${H_2}$ is released once we remove the covering from the top of the test tube.
Reaction follows as: $C{H_3}C{H_2}OH\left( {aq} \right) + Na\left( s \right) \to C{H_3}C{H_2}{O^ - }N{a^ + }(aq) + {H_2}(g) \uparrow$

Thus, option A. hydrogen is the correct option for the given question.

Additional information:
While performing this experiment, sodium should not get in direct contact of any kind of moisture (even with our skin or palms) because it reacts vigorously with water and can cause s, ${H_2}$ serious damage.

Note:
Sodium ethoxide, a major product of this reaction is an example of alkoxide.
Along with this, we should know some uses of hydrogen.
-It is used as a rocket fuel.
-It is used in welding.
-It is used in reduction of ores.
