The viscosity depends on intermolecular forces. Here pentane and hexane has similar type of structure and experience similar type of intermolecular forces. As hexane has higher molar mass than pentane the dispersion force increases in case of hexane. So, the viscosity of pentane will be smaller than the viscosity of hexane.
Neil Princeton will be liquid. So according to figure 11.6, we see that Neil Penton is roughly spherical. Well and contain is cylindrical or Raj A. The spherical Neil Plantain has recreated version for horses. The weaker version forces and the molecules are free to tumble, so we’ll have a smaller but viscosity.
5/25/2016 · For a series of related compounds, viscosity increases with molecular weight. n-pentane (C5H12) and n-hexane (C6H14) are both straight chain compounds with different molecular weights. V iscosity increases with stronger intermolecular forces caused by increase in the molecular weight.
A) What is viscosity ? B) Would you expect the viscosity of n-pentane CH,CH,CH CH2CH, to be larger or smaller than the viscosity of n hexane CH,CH,CH,CH,CH,CH? C) Give a detailed reason for your answer to part B based o 6 intermolecular forces. Draw a phase diagram for water.
(b) Would you expect the viscosity of neopentane, (CH3)4C, to be smaller or larger than the viscosity of n-pentane? (See Fig- ure 11.6 to see the shapes of these molecules.) Linear molecule larger Surface area enhances intermolecular contact and increases dispersion force. n-Pentane (CsH12) 309.4 K bp Spherical molecule-smaller surface area diminishes intermolecular contact and decreases dispersion.

You would expect the viscosity of n-pentane to be larger mainly due to one more carbon atom in the chain. Compare the viscosity of neopentane (CH3)4C and n-pentane. You would expect the viscosity of n-pentane to be larger mainly because the long, cylindrical shape results in stronger dispersion forces when compared to the other hydrocarbon, You would expect the viscosity of n-pentane to be larger mainly because the cylindrical shape results in stronger dispersion forces when compared to the other hydrocarbon .
Q. Compare the viscosity of neopentane, (CH3)4C, and n-pentane. Q. Place the following substances in order of decreasing volatility: CH4, CBr4, CH2Cl2, CH3Cl, CHBr3, and CH2Br2. Q. Use the normal boiling points: propane, C3H8, –42.1?C butane, C4H10, –0.5?C pentane, C5H12, 36.1?C hexane, C6H14, 68.7?C heptane, C7H16, 98.4?C t…
