The Society of Automotive Engineers has established an accepted numerical scale to measure the viscosity of motor oil.?

For example, SAE 40 motor oil has a higher viscosity than an SAE 10 oil. Rank the following hydrocarbons by their expected viscosity.Rank from most to least viscous. CH3CH2CH2CH2CH3 CH3CH2(CH2)8CH2CH3 CH3CH2(CH2)11CH2CH3

They are given in the order of increasing viscosity, so reverse their order.


first is most fluid, last is least fluid. See decane, dodecane, and pentadecane.
