Does use of the rule for organic structures, "Carbon atoms bond together to form a chain," mean that organic structures will always have two end-carbon atoms?

The rule that carbon atoms bond together to form a chain does not inherently mean that organic structures will always have two end-carbon atoms. This is because organic structures can also form rings, where carbon atoms are connected in a cyclic manner, leaving no end-carbon atoms. Therefore, the statement is true for alkanes, which are hydrocarbons with single bonds, as long as they are not cyclic alkanes, which form a ring and thus do not have end-carbon atoms.
