The correct order of boiling point is:

Options

  1. AN H 3 < H F < H 2 O < H 2 O 2
  2. BN H 3 < H F < H 2 O 2 < H 2 O
  3. CN H 3 < H 2 O < H F < H 2 O 2
  4. DH F < N H 3 < H 2 O < H 2 O 2

Correct answer

A. N H 3 < H F < H 2 O < H 2 O 2

Step-by-step solution

N H 3 < H F < H 2 O < H 2 O 2 Boiling point order Number of hydrogen bonding increases boiling point increases, N H 3 has weakest H-bond
