Refractometric study of substituted-2,3‐dihydroquinazolin‐4(1H)‐ones in different binary mixture

Density and refractive index for substituted-2,3‐ dihydroquinazolin‐ 4(1H)‐ ones have been measured in binary mixtures with different composition as per percentage, maintaining constant ligand concentration (0.01M). Measurement of refractive index is done using Abbe’s refractometer. The values of molar refraction (Rm) and polarizability constant (α) have been calculated from the data. Molar refraction and polarizability constant of the investigated systems are increases with increase in percent composition of organic solvents. These parameters and their variation tendencies have been expounded in terms of the interactions between solutes and solvents
