Which from following statements is NOT true according to principles of green chemistry?

Options

  1. AIt is good to use the technique of protection and deprotection of functional group in organic synthesis.
  2. BUse of chemicals derived from plant resource is better than crude oil.
  3. CUse of biodegradable pesticides is advantageous.
  4. DUse of critical CO ₂ as solvent is better than organic solvents.

Correct answer

A. It is good to use the technique of protection and deprotection of functional group in organic synthesis.

Step-by-step solution

Unnecessary derivatisation i.e. addition or removal of protecting groups must be avoided if possible or minimised, as such steps require additional reagents and generate additional waste. The green chemistry principle aims to develop the methodology, where unnecessary steps should be avoided.
