Question

Answer

C₂H₅OH + 2Na → C₂H₅ONa + H₂

Answer

Answer

B) C2H5ONa and H2
When ethanol (C2H5OH) reacts with Na metal, it forms C2H5ONa and hydrogen gas (H2).

Explanation:
1. Chemical Equation:
The reaction can be represented by the following chemical equation:
C2H5OH + Na → C2H5ONa + H2

2. Reactants:
- Ethanol (C2H5OH): It is a colorless liquid alcohol that is commonly used as a solvent and fuel. It has the chemical formula C2H5OH, which indicates that it is composed of two carbon atoms (C2), six hydrogen atoms (H6), and one oxygen atom (O).
- Sodium (Na): It is a highly reactive metal that is commonly found in compounds such as table salt (sodium chloride). Sodium has a single electron in its outermost shell, making it highly reactive and prone to forming ionic compounds.

3. Reaction:
When ethanol reacts with sodium, the sodium metal donates its outermost electron to the ethanol molecule. This electron transfer results in the formation of C2H5ONa, which is the sodium salt of ethanol. The hydrogen gas (H2) is released as a byproduct of this reaction.

4. Formation of C2H5ONa:
C2H5OH + Na → C2H5ONa + H2
The sodium atom donates its electron to the oxygen atom in the ethanol molecule, forming a negatively charged oxygen ion (O-) and a positively charged sodium ion (Na+). The oxygen ion then forms a bond with the carbon atom in the ethanol molecule, resulting in the formation of C2H5ONa.

5. Formation of H2:
C2H5OH + Na → C2H5ONa + H2
The hydrogen atoms in the ethanol molecule are left unreacted and form hydrogen gas (H2) as a byproduct. This gas is released during the reaction.

Overall, when ethanol reacts with sodium, it forms C2H5ONa (sodium ethoxide) and releases hydrogen gas (H2) as a byproduct. This reaction is an example of a single displacement reaction, where sodium displaces hydrogen from ethanol to form a new compound.
