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

  • Correct answer
    A
    It is good to use the technique of protection and deprotection of functional group in organic synthesis.
  • B
    Use of chemicals derived from plant resource is better than crude oil.
  • C
    Use of biodegradable pesticides is advantageous.
  • D
    Use of critical $\mathrm{CO}_2$ as solvent is better than organic solvents.

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.

Hence, the correct answer is option: 'A'.
