A) more polar than \[{{H}_{2}}S\]
B) more or less identical in polarity with \[{{H}_{2}}S\]
C) less polar than \[{{H}_{2}}S\]
D) None of these
Correct Answer: A
Solution :
[a] Polarity of bond depends on difference in electronegativity of the two concerned atoms. \[{{H}_{2}}O\] is more polar than \[{{H}_{2}}S\] because oxygen (in\[O-H\]) is more electronegative than sulphur (in\[S-H\]).
