Question:

(a) Would you expect the viscosity of n-pentane, CH3CH2CH2CH2CH3, to be larger or smaller than the viscosity of n-hexane (3.26 × 10-4kg/m-s)(from Table 11.4)?
(b) If you compared their viscosities at 270 K, would you expect the viscosity of neopentane, (CH3)4C, to be smaller or larger than n-pentane? (See Figure 11.6 to see the shapes of these molecules.)
