Boiling point elevations are directly proportional to the molality of a solution, but chemists have found […] Boiling point elevation refers to the tendency of a solvent’s boiling point to increase when an impurity (a solute) is added to it. Cyclopentane is in the class of cycloalkanes, being alkanes that have one or more rings of carbon atoms. Cycloalkanes are types of alkanes that have one or more rings of carbon atoms in their structure. I’m looking at a chart in my book, and while cycloheptane has a higher boiling point than cyclohexane like I’d expect, cycloheptane has a melting point of −12 °C, while cyclohexane has a melting point of 6.6 °C.
Its melting point is −94 °C and its boiling point is 49 °C. It may be derived by Clemmensen reduction from cycloheptanone. Fusion (melting) point Data from NIST Standard Reference Database 69: NIST Chemistry WebBook The National Institute of Standards and Technology (NIST) uses its best efforts to deliver a high quality copy of the Database and to verify that the data contained therein have been selected on the basis of sound scientific judgment. InChI ... Normal Boiling Point Temperature (K). Boiling Point: 69ºC: Melting Point-95ºC: Flash Point-23.3ºC: Viscosity (cP) 0.300 at 25ºC: Dielectric Constant: 1.89 at 20ºC: UV cutoff: 210 nm: Refractive Index: 1.375 at 20ºC: Vapor Pressure: 132 mm Hg (20°C) Vapor Density: 3 (vs. air) Cycloheptane: EINECS: 206-030-2 CAS No. Synthesis Reference(s): Journal of the American Chemical Society, 89, p. 3911, 1967 The Journal of Organic Chemistry, 46, p. 4111, 1981 Two possibilities here: Someone on Quora is a world-renowned expert on cycloheptane and knows the density at its normal boiling point because it’s a number s/he uses every day is his expertness. Boiling Point : 81C (178F) Melting Point : 7C (45F) Vapor Density (Air=1) : 3.0 . In fact, the more solute that is added, the greater the change in the boiling point. indicates value is 100% or more of LEL.
