B.
more or less identical in polarity with $${H_2}S$$
C.
less polar than $${H_2}S$$
D.
None of these
Answer :
more polar than $${H_2}S$$
Solution :
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 $$\left( {{\text{in}}\,O - H} \right)$$ is more electronegative than sulphur $$\left( {{\text{in}}\,S - H} \right).$$
