How does the shape of a branched alkane, like neopentane, affect its boiling point compared to a straight-chain alkane, like n-pentane?
The spherical shape of neopentane increases surface area and strengthens van der Waals forces, leading to a higher boiling point than n-pentane.
The spherical shape of neopentane reduces surface area and weakens van der Waals forces, leading to a lower boiling point than n-pentane.
The shape has no effect on the boiling point; both neopentane and n-pentane have similar boiling points.
The spherical shape of neopentane traps heat more effectively, leading to a higher boiling point than n-pentane.
