Answer 2

Smaller E-factor of a reaction implies lesser C) wastage.

E-factor:

• Although atom economy is a valuable notion, the E factor, which is defined as the following: is a more precise way to gauge how environmentally acceptable a chemical manufacturing process is.
• E factor = Total mass of waste from process/Total mass of product
• Byproduct waste, residual reactants, solvent losses, used catalysts and catalyst supports, and any other waste that can be categorized as waste are all taken into consideration by the E factor.
• The computation is based on the definition of waste.
• Since water is typically safe and a considerable byproduct of many chemical processes, its bulk is typically excluded from the calculation of the total mass of waste.
• However, it might be used in procedures where it is highly contaminated and difficult to recover in a state that is pure enough to utilize or discharge to a facility that treats public wastewater.
