Identifying the Environmentalist Bleaching Agent
The question asks to identify the compound used as a bleaching agent, particularly by environmentalists. This implies looking for a compound that is effective for bleaching but also relatively environmentally friendly compared to alternatives.
Evaluating Bleaching Agent Options
Let's analyze the given options:
- Tetra chloroethane: This is a chlorinated hydrocarbon primarily used as a solvent. It is toxic and not commonly used as a bleaching agent, especially from an environmental perspective.
- Acetanilide: This compound is used medically as an analgesic and antipyretic. It is not known for bleaching properties.
- Hydrogen peroxide (H2O2): This is a strong oxidizing agent widely used as a bleaching agent in various industries (like paper and textiles) and also in household products. It decomposes into water and oxygen, making it relatively environmentally friendly compared to chlorine-based bleaches.
- Acetone: This is a common organic solvent and is not used as a bleaching agent.
Conclusion on Bleaching Agent
Based on its properties as a powerful oxidizing agent and its relatively eco-friendly decomposition products (water and oxygen), Hydrogen peroxide is the compound used as a bleaching agent, particularly favored in environmentally conscious applications.
