Pentane and 2-Methyl butane have the same?
Correct answer: C. percentage composition
- A. Boiling point
- B. melting point
- C. percentage composition
- D. Structural formula
Explanation
Both pentane and 2-methylbutane have the same elements (carbon and hydrogen) and the same number of each element (5 carbon atoms and 12 hydrogen atoms). Therefore, they share the same percentage composition: 83.33% carbon and 16.67% hydrogen
