MCQ
The highest boiling point is expected for:
  • A
    Isooctane
  • B
    n-Octane
  • C
    2, 2, 3, 3-Tetramethyl butane
  • D
    n-Butane
✓

Answer

  1. n-Octane

Explanation:

Boiling point is characterized as the specific temperature at which the vapour pressure of the fluid is equivalent to the environmental pressure.

Among the given options

n-Octane is a straight-chain exacerbate that has a very large surface area. Along these lines, there are more van der Waals forces of attraction, bringing about high boiling points.
