It can be, in long chain hydrocarbons as shown in the image.
Branched chain hydrocarbons have a lower tendency to knock compared to straight-chain hydrocarbons due to their increased resistance to autoignition. Ring hydrocarbons, such as aromatics, also have lower knock tendencies because of their stable structures. Overall, both branched chain and ring hydrocarbons are preferred in high-performance engines to reduce knocking.
The are linear compounds.
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.
I have heard that Methane can be used to form longer chain hydrocarbon fuels, -why not the much higher energy bonded Acetylene?
A chain hydrocarbon has a long molecule containing only carbon and hydrogen.

Heavy Fuel Oil is what if refereed to as the heavies, is the long chain hydrocarbons in crude that can not be distilled at 350 F. The products includes greases, waxes, plastics, asphalts, tar etc. The HFO can be further process to separate the different products or can be cracked, a process that breaks the long chain hydrocarbons in to shorter chain hydrocarbons and distilled into LNG, gasoline, diesel, kerosene etc.

Short-chain hydrocarbons have fewer carbon atoms (usually less than 5) and are typically gases or liquids at room temperature, while long-chain hydrocarbons have more carbon atoms (usually more than 5) and are often solids or high-viscosity liquids at room temperature. Short-chain hydrocarbons are more volatile and have lower boiling points compared to long-chain hydrocarbons.

A triglyceride is made of three long chain fatty acids (hydrocarbons) attached to one molecule of glycerol.
Plastics are almost always made of long-chain hydrocarbons - consequently you will find hydrogen and carbon in plastics
Straight-chain hydrocarbons ignite very easily; in a vehicle, they would ignite before they reached the engine. Branched hydrocarbons are not as reactive so they are used for fuel such as petrol.
Cyclic hydrocarbons form a circular shape. Like an O chain structures are linear structures. Like VVVVV
