Step 1
Which statement about butane is correct?
Answer
To determine which statement about butane is correct, we should consider:
-
Size of the molecule: Butane (C₄H₁₀) is relatively small in terms of hydrocarbon structures, typically classified as a small molecule in the context of hydrocarbons.
-
Intermolecular Forces: Butane primarily exhibits van der Waals forces (dispersion forces), which are generally considered weak compared to stronger forces like hydrogen bonding.
Based on this analysis:
- The correct answer is D: "Butane is a small molecule and has weak intermolecular forces."
