Question

Hazardous effects of a substance can be reduced by}

• A. increasing its bioavailability
• B. minimising its biodiversity
• C. using protecting groups
• D. using solvents

Hint:

Reducing reactivity (e.g., using protecting groups) helps minimize hazardous effects in chemical processes.

Answer 1

The Correct Option is C

Concept: In chemistry and environmental safety, hazardous effects of substances can be reduced by modifying their reactivity. Step 1:Understand protecting groups.
Protecting groups are used to:

• Temporarily block reactive sites
• Reduce unwanted or harmful reactions

Step 2:Evaluate options.}

• Increasing bioavailability $\rightarrow$ Increases effect (incorrect)
• Minimising biodiversity $\rightarrow$ Irrelevant
• Using protecting groups $\rightarrow$ Reduces hazardous reactivity (correct)
• Using solvents $\rightarrow$ Does not necessarily reduce hazard

Final Answer: \[ {\text{using protecting groups}} \]
