Give an example of a green solvent and explain its benefits.

• Supercritical carbon dioxide (CO2) is a green solvent. It is non-toxic, non-flammable, and readily available as a byproduct of various industrial processes.

• Methanol is a green solvent. It is toxic and can cause blindness, but it is cheap.

• Chloroform is a green solvent. It is toxic and carcinogenic, but it looks nice.

• Acetone is a green solvent. It is highly toxic and flammable, but it smells nice.

Explain the concept of atom economy in the context of green solvents.

• Atom economy is the concept of using atoms as a unit of currency in the chemical industry.

• Atom economy is the efficiency of a chemical reaction in utilizing all the atoms in the starting materials to form the desired product, minimizing waste and maximizing the use of raw materials.

• Atom economy is the measure of the weight of the product compared to the weight of the reactants.

• Atom economy is the process of converting atoms into energy in a chemical reaction.

Discuss the role of ionic liquids as green solvents.

• Ionic liquids act as green solvents due to their low volatility, non-flammability, and recyclability.

• Ionic liquids are highly volatile and flammable, making them unsuitable as green solvents.

• Ionic liquids cannot be recycled, making them environmentally unfriendly as solvents.

• Ionic liquids have a high environmental impact and contribute to pollution, making them unsuitable as green solvents.
