Nov 30, 2011 · C8H18>C6H14>C4H10>C3H8. All these compounds are alkanes, saturated hydrocarbons with the general formula CnH2n+2. The boiling point depends on the intramolecular forces of attraction (van der Waals) which here depend on the molecular mass so the hydrocarbons are listed in order of decreasing molecular weights. A good indicator of bonding between molecules is there boiling/melting points. In the case of C3H8 it has a boiling point of -42C which means the forces C3H8 (propane) is not polar. The reason been that the electronegativity of the atoms (hydrogen) around the central atoms (carbon) cancel out...Conversely, a substance with a low boiling point must have weak intermolecular interactions, surmountable even at low temperature. First, the most dominant trend in the boiling points is that, within a single group, the boiling points of the hydrides increase as we move down the periodic table.

None of these have hydrogen bonding. 2. None of these have dipoles. 3. Bigger molecules will have stronger London dispersion forces. We discussed vapor pressure and/or boiling point in CH301 as it related to intermolecular forces (IMF). Boiling point and vapor pressure are two sides of the same coin. The boiling point is the temperature at which the vapor pressure equals the total pressure. When comparing vapor pressures we need to be making comparisons at the same temperature.

K b is the boiling point constant for H 2 O, and its value is 0.512 ºC / m. ΔT b = 0.512 ºC / m x 0.0585 m = 0.0300 ºC Since ΔT b = T b - T b º, where T b is the boiling point of the solution and T b º is the boiling point of the solvent (H 2 O), which = 100.00 ºC, rearrange to solve for T b . For many purposes we can treat propane C3H8 as an ideal gas at temperatures above its boiling point of −42.°C Suppose the temperature of a sample of propane gas is lowered from 19.0°C to −11.0°C, and at the same time the pressure is changed.

Propane remains a popular choice for barbecues and portable stoves because its low boiling point of −42 °C (−43.6 °F) makes it vaporize as soon as it is released from its pressurized container. Therefore, no carburetor or other vaporizing device is required; a simple metering nozzle suffices.
Can you come through chordsExample #4: Using the heat of vaporization for water in J/g, calculate the energy needed to boil 50.0 g of water at its boiling point of 100 °C. Solution: multiply the heat of vaporization (expressed in J/g) by the mass of the water involved. (2259 J/g) (50.0 g) = 112950 J = 113 kJ 2) A 55-g sample of a gaseous fuel mixture contains 0.51 mole fraction propane, C3H8; the remainder of the mixture is butane, C4H10.
