A) \[{{C}_{2}}{{H}_{5}}OH\]
B) \[C{{H}_{3}}OH\]
C) \[{{H}_{2}}O\]
D) \[{{C}_{6}}{{H}_{6}}\]
Correct Answer: C
Solution :
Surface tension of \[{{H}_{2}}O\]is maximum due to maxi- mum hydrogen bonding in comparison to \[{{C}_{2}}{{H}_{5}}OH,\]\[C{{H}_{3}}OH,{{H}_{2}},\]and\[{{C}_{6}}{{H}_{6}}.\]The order of H-bonding is\[{{H}_{2}}O>C{{H}_{3}}OH>{{C}_{2}}{{H}_{5}}OH\] (Benzene does not form H-bond)
