Possible Solution:
Identification of Organic Solvent P:
To determine the identity of organic solvent P, we need to calculate its molecular mass. Given that the molecular mass of P is 46 u, we can compare it with the known molecular masses of organic compounds to find a suitable match.
The molecular mass of P (46 u) corresponds to that of ethanol (C2H5OH). Therefore, the organic solvent P is likely to be ethanol.
Oxidation of Ethanol:
When ethanol (P) is oxidized, it can undergo different reactions depending on the presence or absence of an oxidizing agent.
1) Oxidation of Ethanol in the Presence of an Oxidizing Agent:
In the presence of an oxidizing agent, ethanol can be oxidized to acetaldehyde (CH3CHO) or further to acetic acid (CH3COOH).
The equation for the oxidation of ethanol to acetaldehyde is as follows:
C2H5OH + [O] → CH3CHO + H2O
2) Oxidation of Ethanol in the Absence of an Oxidizing Agent:
In the absence of an oxidizing agent, ethanol can undergo dehydration to form ethene (C2H4).
The equation for the dehydration of ethanol to ethene is as follows:
C2H5OH → C2H4 + H2O
Reaction of Ethanol (P) with the Product of Oxidation:
The product formed in the oxidation of ethanol (P) with an oxidizing agent is acetaldehyde (CH3CHO). Acetaldehyde can react further to form a fruity smelling compound.
1) Reaction of Acetaldehyde with Oxygen:
CH3CHO + O2 → CH3COOH
2) Fruity Smelling Compound:
The fruity smelling compound formed in the reaction is ethyl acetate (CH3COOC2H5).
Treatment of Ethyl Acetate with an Alkali:
When ethyl acetate (fruity smelling compound) is treated with an alkali, it undergoes a process called saponification.
Saponification is the hydrolysis of an ester in the presence of an alkali, resulting in the formation of an alcohol (ethanol) and a salt (sodium acetate). The reaction is as follows:
CH3COOC2H5 + NaOH → CH3COONa + C2H5OH
In this reaction, ethyl acetate (CH3COOC2H5) reacts with sodium hydroxide (NaOH) to form sodium acetate (CH3COONa) and ethanol (C2H5OH). This process is commonly used in the production of soaps.
Summary:
- The organic solvent P is identified as ethanol (C2H5OH) based on its molecular mass.
- Ethanol can be oxidized to acetaldehyde (CH3CHO) or further to acetic acid (CH3COOH) in the presence of an oxidizing agent.
- In the absence of an oxidizing agent, ethanol can undergo dehydration to form ethene (C2H4).
- The product of oxidation, acetaldehyde (CH3CHO), can
