Options

  1. AElectromagnetic waves travel in a medium with a speed of 2 × 10 ^ 8 ms^ - 1 . The relative permeability of the medium
  2. BElectromagnetic waves travel in a medium with a speed of 2 × 10 ^ 8 ms^ - 1 . The relative permeability of the medium
  3. CElectromagnetic waves travel in a medium with a speed of 2 × 10 ^ 8 ms^ - 1 . The relative permeability of the medium
  4. DElectromagnetic waves travel in a medium with a speed of 2 × 10 ^ 8 ms^ - 1 . The relative permeability of the medium

Correct answer

D. Electromagnetic waves travel in a medium with a speed of 2 × 10 ^ 8 ms^ - 1 . The relative permeability of the medium

Step-by-step solution

Sugar has an ester functional group (−O−CO−R)\left(- O - CO - R\right), which gets hydrolyzed in an alkaline medium to give hemi-acetal, which then acts as a reducing sugar.
