The correct order of boiling point is

Options

  1. AT 2 < D 2 < H 2
  2. Bn-pentane < neo-pentane
  3. CX e < A r < H e
  4. Dm-nitrophenol > o-nitrophenol

Correct answer

D. m-nitrophenol > o-nitrophenol

Step-by-step solution

Here option D is incorrect while rest are correct as follows A T 2 > D 2 > H 2 [BP ∝ mol. wt.] B n-pentane > neo-pentane [BP ∝ VWf ∝ contact area ∝ 1 B r a n c h i n g ] C X e > A r > H e [BP ∝ mol. wt.] D
