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.
A hydrocarbon that is very viscous and not very flammable is made of a long chain hydrocarbon.
short chain hydrocarbons have a low boiling and melting point whereas high chain hydrocarbons have a higher boiling and melting point. Also, short chain hydrocarbons have a low density and higher ones have a higher density. :)
A chain hydrocarbon has a long molecule containing only carbon and hydrogen.
A long hydrocarbon chain without any oxygen bonds
No, fatty acids are long-chain carboxylic acids, typically made up of a hydrocarbon chain with a carboxylic acid group at one end. They do not have a four-ring hydrocarbon structure.
For example the palmitic acid.
The most viscous fraction would be one with a high molecular weight and long chain length, such as heavy oils or polymers. These fractions have stronger intermolecular forces, leading to higher viscosity.
Sodium lauryl sulfate contains a sulfate group (-OSO3Na) and a hydrocarbon chain, which is a long alkyl chain.
I have heard that Methane can be used to form longer chain hydrocarbon fuels, -why not the much higher energy bonded Acetylene?
A soap molecule contain a long chain of hydrocarbon which is hydrophobic and a short ionic part which is hydrophilic, when oily and greasy substance comes in the contact of soap, then long chain of hydrocarbon get attach with them and form a substance which is hydrophilic ( soluble in water ) and due to that oily an greasy substance removed form cloths.
The functional groups in palmitic acid are a carboxylic acid group (COOH) and a long hydrocarbon chain (C15H31-).
Sodium acetate and sodium propanoate are poor soaps because these soaps have a small hydrocarbon chain to bind to dirt. ... The hydrocarbon chain of these soaps is not long enough and therefore, there are fewer non-polar substances that are available for the molecules to bind to fats, oils, and dirt.
