Answer:
B.
General Formulas and Concepts:
Chemistry - Organic
- Hydrocarbons
- Bond-Line Notation: Each "arrow" point represents a carbon and the lines represent a bond between the carbons. Hydrogens are assumed added when drawing the molecular formulas
Step-by-step explanation:
We are given C₈H₁₈. We need a Bond-Line notation where there are 8 "arrow" points (which represent Carbon). We can disregard the Hydrogens as they are assumed to take the rest of the bonds.
Only option B has a value of 8 carbons, represented by the "arrow" points. Therefore, it is the correct answer.
