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.
What else can I help you with?
How couid you justify additive and constitutive property of parachor?
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.
What is the energy released in the combustion of hexane?
The energy released in the combustion of hexane is approximately 46.8 megajoules per gram of hexane combusted.
Is hexane more polar than dichloromethane?
No, hexane is less polar than dichloromethane. Hexane is a nonpolar solvent because it contains only carbon and hydrogen atoms, while dichloromethane has polar covalent bonds due to the presence of chlorine atoms.
Is ice more dense than hexane?
No, ice is not more dense than hexane. Ice has a density of about 0.92 g/cm³, while hexane has a density of approximately 0.66 g/cm³. This lower density of hexane means that ice will float on hexane when the two are combined.
Is hexane a compound or mixture?
Hexane is a compound. It is a simple hydrocarbon molecule consisting of six carbon atoms and 14 hydrogen atoms.

What is parachor value of chloroform?
The parachor value of chloroform is approximately 79 cal/cm³. Parachor is a measure of the ability of a substance to spread over the surface of another substance. In the case of chloroform, its parachor value reflects its molecular structure and interactions with other substances.
What is parachor value of acetic acid?
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.
What is the pH of hexane?
Hexane is a nonpolar molecule and does not dissociate in water to form ions, so it does not have a pH value.
What is the energy released in the combustion of hexane?
The energy released in the combustion of hexane is approximately 46.8 megajoules per gram of hexane combusted.
What is parachor value of carbon dioxide?
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.
What is difference between hexane and n-hexane?
Hexane is a hydrocarbon with the chemical formula C6H14. n-hexane is the unbranched isomer of hexane as there exists four more branched isomers of hexane
Is hexane more polar than dichloromethane?
No, hexane is less polar than dichloromethane. Hexane is a nonpolar solvent because it contains only carbon and hydrogen atoms, while dichloromethane has polar covalent bonds due to the presence of chlorine atoms.
What is the application of parachor?
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.
What is the unit of parachor in cgs system?
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
