Answer 2

Ethanol: Definition, Structure and reaction with Sodium and Excess of Concentrated sulfuric acid.

Ethanol:

• It is the second member of alcohol family with molecular formula $C_2H_5OH$.

Structure of ethanol:

• Ethanol is composed of the following atoms:

1. 2 atoms of carbon
2. 5 atoms of hydrogen
3. -OH group

• Kindly refer to the attachment for the structure.

Reactions with sodium and sulfuric acid:

1. Reaction with sodium:

• Ethanol reacts with sodium and forms sodium ethoxide and releases hydrogen gas.
• The reaction involved is as follows:

$2C_2H_5OH+2Na\rightarrow 2C_2H_5ONa+H_2$

2. Reaction with Excess of concentrated sulfuric acid at 443K:

• In the presence of Excess of concentrated sulfuric acid at 443K, ethanol undergoes dehydration.
• The reaction involved is as follows:

$2 C_{2} H_{5} O H \stackrel{H_{2} S O_{4} / 443 K}{\longrightarrow} C H_{2}=C H_{2}$
