Question
The branching of alkanes that produces symmetrical structures :
Correct Answer
Option A is the correct answer.
Detailed Explanation
Symmetrical branching (like in neopentane) leads to more compact molecules that have lower surface area, reducing van der Waals forces and lowering boiling points. However, symmetrical molecules pack better in the solid state, increasing melting points.
Hint
How does symmetry affect boiling point and melting point differently?
