KVPY Sample Paper KVPY Stream-SX Model Paper-31

The correct order of strength of H-bond in the following compound -

A) \[{{H}_{2}}O>{{H}_{2}}{{O}_{2}}>HF>{{H}_{2}}S\]

B) \[HF>{{H}_{2}}{{O}_{2}}>{{H}_{2}}O>{{H}_{2}}S\]

C) \[HF>{{H}_{2}}O>{{H}_{2}}S>{{H}_{2}}{{O}_{2}}\]

D) \[HF>{{H}_{2}}O>{{H}_{2}}{{O}_{2}}>{{H}_{2}}S\]

Correct Answer: D

Solution :

Strength of H-bonding is higher in \[{{H}_{2}}O,\]than \[{{H}_{2}}{{O}_{2}}\] because the amount of formal negative charge on oxygen atom in case of water is more than that of \[{{H}_{2}}{{O}_{2}}.\]
