Viscosity also increases with carbon chain length, at least of linear hydrocarbons.
As the chain length of hydrocarbons increases, their boiling point and viscosity also tend to increase. Longer chain hydrocarbons are usually less volatile and have higher boiling points compared to shorter chain hydrocarbons. Additionally, longer chain hydrocarbons are typically more viscous and have higher melting points.
Polymethyl methacrylate (PMMA), commonly known by the brand name Plexiglas, is a synthetic polymer that tends to become harder as the number of carbon atoms in the polymer chain increases. This increase in chain length leads to a higher degree of crystallinity, which contributes to the material's strength and hardness.
Generally, as the carbon chain length increases, the melting point of a compound also tends to increase. This is because longer carbon chains result in stronger intermolecular forces, such as London dispersion forces, leading to a higher melting point. Shorter carbon chains have weaker intermolecular forces, so they typically have lower melting points.
Petrol typically consists of hydrocarbons with a chain length of about 5-10 carbon atoms. These are considered medium-length hydrocarbons, rather than short-chain hydrocarbons which usually have 1-4 carbon atoms.
Polyethylene gets harder as the number of carbon atoms increases.
When the chain length of carbon increase the flammability decrease.
As the carbon chain length of a hydrocarbon increases, its volatility generally decreases. This is because longer carbon chains have stronger intermolecular forces, such as van der Waals forces, which make it harder for the molecules to escape into the gas phase. Shorter chain hydrocarbons are typically more volatile and have lower boiling points compared to longer chain hydrocarbons.

Longer chain hydrocarbons are usually less volatile and have higher boiling points compared to shorter chain hydrocarbons. Additionally, longer chain hydrocarbons are typically more viscous and have higher melting points.
As the length of the carbon chain increases in alkanes, the intermolecular forces (London dispersion forces) between the molecules also increase. These forces cause the molecules to stick together more strongly, making the substance thicker and less runny. Additionally, longer carbon chains have higher molecular weights, leading to increased van der Waals forces that further contribute to the thicker consistency.

This is because the longer the carbon chain, it spreads it out more equally which causes the carbon to get a lot more thicker and less runny Answered by a natural scientist who tries the experiments

Typically the shorter the carbon chain, the LESS viscous the hydrocarbon. The longer the chain, the MORE viscous the hydrocarbon. For example consider the viscosity and molecular size in: Gasoline < Diesel < Motor Oil < Tar Viscosity increases with the molecular size and length of hydrocarbon chain.
As chain length of alcohols increases, viscosity generally increases. Longer chain alcohols have more surface area for intermolecular forces to act upon, leading to stronger cohesive forces between molecules and higher resistance to flow. This increase in viscosity is due to the greater entanglement and interaction between longer chain molecules.
Generally speaking, boiling points increase as carbon chain length increases. This is because there are more atoms present in the hydrocarbon molecule and therefore more intermolecular forces (eg Van der Waals') that must be overcome. In addition the now heavier molecule requires greater energy (heat) to make the phase change to a gas. However, branching decreases boiling point; branched hydrocarbons cannot pack together as closely as unbranched ones, and so intermolecular forces are less strong. So, for example, the bp is higher for butane than 2-methylpropane (even though they contain the same number of C and H atoms).

As a general rule the longer the carbon chain the greater the Rf value.
