Answer to Question #113853 in Chemistry for DEEPAK SINGH

Question

Calculate the molar refractivity of allyl chloride at a temperature at which it's density is 0.938g cm^-3 the experimentally observed value of refractive index at this temperature is 1.3715.

Answer 1

Solution:

CH₂=CHCH₂Cl or C₃H₅Cl - allyl chloride

The molecular weight of allyl chloride is 76.52 g/mol.

The molar refractivity [R] (cm³ mol^-1) is a constitutive-additive property that is calculated by the Lorenz-Lorentz formula:

where M is the molecular weight, n it is the refraction index and p the density.

Therefore,

Answer: The molar refractivity of allyl chloride is 18.52 cm³ mol^-1.
