Viscosity is defined as resistance of a fluid (liquid or gas) to a change in shape, or movement of neighboring portions relative to one another. Viscosity denotes opposition to flow. The reciprocal of the viscosity is called the fluidity, a measure of the ease of flow. Based on what you have learned about the boiling and melting points of alkanes as the number of carbons in their carbon chain increases, what do you think is the trend for hydrocarbon viscosity
