Boiling point and stability
WebBoiling Point and Melting Point in Organic Chemistry Stability of Alkenes There are two factors to consider when deciding the more stable alkene. One is the sterics which is expressed when comparing cis and trans … WebFor example, at 1 atm, the boiling point is 100 °C. Notice that the liquid-vapor curve terminates at a temperature of 374 °C and a pressure of 218 atm, indicating that water cannot exist as a liquid above this temperature, regardless of the pressure.
