110.4 is the value of parachor for methanol
The parachor value of acetic acid is approximately 11.92 cal/cm^3. Parachor is a measure of molecular surface tension and is used to compare the cohesive properties of different substances.
Chloroform is a clear, colorless liquid.
The rheochor value for chloroform is approximately 44.6 nm². This value indicates how strongly a substance interacts with a solvent or dispersant.
Sugden's parachor contribution values for molecular compounds were subsequently improved by Mumford and Phillips (1929), Quayle (1953) and Knotts et al. (2001) S.A. Mumford, J.W.C. Phillips, J. Chem. Soc. (1929) 2112-2133. O.R. Quayle, Chem. Rev. 53 (1953) 439-489. T.A. Knotts, W.V. Wilding, J.L. Oscarson, R.L. Rowley, J. Chem. Eng. Data 46 (2001) 1007-1012.

The additive property of parachor suggests that the parachor value of a mixture can be calculated by summing the parachor values of the individual components. This can be justified by understanding that the parachor value is a measure of the cohesive energy density of a substance, which depends on its molecular structure. The constitutive property of parachor, on the other hand, implies that the parachor value is a fundamental property of a substance, determined by its chemical composition and structure.
The parachor value of acetic acid is approximately 11.92 cal/cm^3. Parachor is a measure of molecular surface tension and is used to compare the cohesive properties of different substances.
The parachor value of hexane can be estimated using its molecular weight and density. Hexane (C6H14) has a molecular weight of approximately 86.18 g/mol and a density of about 0.6548 g/cm³. The parachor value is calculated as the product of the molecular weight and a constant related to the density, resulting in a parachor value of approximately 60.5. This value reflects the cohesive forces in the liquid phase and is useful in characterizing its physical properties.

~13. Evidence: t-butoxide (pKa ~18) can deprotonate it to form dichlorocarbene.
For Iodine in Chloroform & water, the distribution ratio is 250; hence at equilibrium, the iodine concentration in the chloroform phase is 250 times then in the water phase.
Parachor is a useful parameter in physical chemistry and materials science, primarily applied to characterize the surface tension of liquids and the properties of polymers. It helps in understanding the intermolecular forces within a solution or between different phases. Additionally, parachor values can aid in predicting the behavior of substances in various applications, such as in the formulation of emulsions, foams, and coatings. By analyzing parachor, researchers can gain insights into molecular structure and dynamics.
The unit of parachor in the cgs (centimeter-gram-second) system is typically given in cubic centimeters to the power of 1.5 per dyne to the power of 1/2 (cm^3/2·dyne^-1/2). So, the unit of parachor in the cgs system can be expressed as: Parachor unit = cm 3 / 2 ⋅ dyne − 1 / 2 Parachor unit=cm 3/2 ⋅dyne −1/2
