Explanation:

What is Click Chemistry?

  • Click chemistry refers to a collection of organic reactions that proceed rapidly and selectively under mild conditions to covalently link molecular components. (Statement 1 is not correct)
  • Click reaction uses only readily available reagents and is insensitive to oxygen and water. This aspect makes it widely acceptable. (Statement 2 is not correct)
  • Applications of Click Chemistry:
    • Drug discovery: Click chemistry has found increasing applications in all aspects of drug discovery in medicinal chemistry, such as for generating lead compounds through combinatorial methods.
    • Bioconjugation: Click chemistry is rigorously employed in proteomics and nucleic research via bioconjugation.
    • Radiochemistry: In radiochemistry, selective radiolabeling of biomolecules in cells and living organisms for imaging and therapy has been realized by click reactions.
    • Nanoparticle modification: Click chemistry is generally used to conjugate the ligands, folate groups to the nanoparticles, which are then used for nanoparticle drug delivery.

Q) Consider the following statements regarding the quantum theory.

  1. By start of 20th century, scientists observed that tiny sub-atomic particles like protons or electrons were not consistent with the classical Newtonion laws of physics.
  2. The prediction made by Quantum Theory was obeyed by the sub-atomic particles. This was proved through an experiment which proves entanglement.

Which of these statements are correct?

  1. Both 1 and 2
  2. 2 only
  3. 1 only
  4. Neither 1 nor 2

Explanation:

About quantum theory:

  • By start of 20th century, scientists observed that tiny sub-atomic particles like protons or electrons were not consistent with the classical Newtonion laws of physics. (Statement 1 is correct)
  • Further studies in this regard gave rise to Quantum Theory, which described the bizarre behaviour of sub-atomic particles with remarkable accuracy.
  • Properties:
    • Superimposition: A property known as superimposition allowed particle to exist simultaneously at multiple locations. The chance of finding the particle at any given place was based on probabilistic calculations, and once it was found at one location, it ceased to exist at all other places.
    • Entanglement: If two particles had ‘interacted’ with each other at some stage, they were found to have got ‘entangled’ in a way that the behaviour of one produced an instantaneous reaction in the other. This was possible even if they were no longer connected in any way and were separated by very large distances.
    • Problems with quantum theory: The prediction made by Quantum Theory was obeyed by the sub-atomic particles. The only issue was that an experiment to test a phenomenon like entanglement did not appear feasible. (Statement 2 is not correct)

Q) Recently in news, Bell’s inequality, is a theorem which relates to inequality in which of the following subjects?

  1. Physical inequality
  2. Zoonotic inequality
  3. Chemical inequality
  4. Mathematical inequality

Explanation:

Bell’s inequality

  • In the 1960s, John Stewart Bell developed the mathematical inequality that is named after him.
  • This Inequality stated that if a large number of measurements of the hidden variables were conducted, the correlation between the results could not exceed a certain value.
  • This in turn meant that no local hidden variable theory could reproduce all the results of quantum mechanics.
  • But quantum mechanics predicts that a certain kind of experiment can violate Bell’s inequality. This results in a stronger correlation than would otherwise be possible.

Q) Consider the following statements regarding the Food and Agriculture Organisation
