Quizplus · Accepted Answer

A line in a line-angle formula represents a carbon-carbon bond. A vertex (or the end of a line) represents a carbon atom, not a hydrogen atom. Hydrogen atoms are not explicitly shown in line-angle formulas; they are implied based on the valency of carbon. A line ending in space does not specifically represent a methylene group; it simply indicates the end of a carbon chain, which could be a methyl group if it's at the end or part of a longer chain.
