Witryna10 paź 2024 · Comprehensive and accurate measurements of the speed of sound in liquid n-pentane and isopentane were carried with a double-path-length pulse-echo instrument. The measurements cover the temperature ranges between 200 and 420 K for n-pentane and between 220 and 420 K for isopentane with pressures up to 100 … WitrynaThe elongated shape of n -pentane provides a greater surface area available for contact between molecules, resulting in correspondingly stronger dispersion forces. The more compact shape of isopentane offers a smaller surface area available for intermolecular contact and, therefore, weaker dispersion forces. grand haven cinema https://tlrpromotions.com

Witryna12 lut 2024 · $\begingroup$ Your rule of thumb that the smallest (lowest MW) alkane will have the lowest BP and the largest (highest MW) will have the largest is just wrong. It works in this case because the molecules are all very small, "essentially" linear. Branching in higher weight alkanes makes it impossible to predict BP solely on the … Isopentane, also called methylbutane or 2-methylbutane, is a branched-chain saturated hydrocarbon (an alkane) with five carbon atoms, with formula C 5H 12 or CH(CH 3) 2(C 2H 5).
