Question

Molar refraction is product of specific refraction and

Answer 1

Answer:

The product of molecular weight, M and specific refraction r gives molecular/molar refraction R in Cm3 units. Therefore, polarizability a of a substance can be determined by measuring the refractive index of the substance.

Answer 2

Molar refraction is the product of specific refraction and molecular weight.

Explanation:

• The product of molecular weight, M, and specific refraction r is molar refraction.
• Molecular/molar refraction R in $cm3$ units.
• The polarizability of a substance can be determined by measuring the refractive index of the substance.
• The index of refraction (n) and molar refraction (RD) are indications of the way in which a molecule interacts with light.
• The index of refraction is the ratio of the speed of light in a vacuum (c) to the speed of light in the medium (v)
• It's simply a measure of the polarizability of the mole of a compound element. It's given by: $A = (4/3) \pi N \alpha$
