The correct order of strength of H-bond in the following compounds is

Options

  1. AH 2 O > H 2 O 2 > H F > H 2 S
  2. BH F > H 2 O 2 > H 2 O > H 2 S
  3. CH F > H 2 O > H 2 S > H 2 O 2
  4. DH F > H 2 O > H 2 O 2 > H 2 S

Correct answer

B. H F > H 2 O 2 > H 2 O > H 2 S

Step-by-step solution

The correct order of strength of H-bond is H F > H 2 O 2 > H 2 O > H 2 S Strength of H-bonding is higher in H 2 O 2 than H 2 O , because the amount formal negative charge on oxygen atom in case of water is more than that of H 2 O 2 .
