Answer:
a. the electrons shared between the oxygen and hydrogen atoms spend more time around the oxygen atom nucleus than around the hydrogen atom nucleus.
Explanation:
Water molecule is a polar molecule , and hence , the atom can attain the respective partial positive and negative charge on them .
The difference in the electronegativity gives rise to the partial positive and negative charge .
Since , oxygen atom is more electronegative in comparison to hydrogen atom , and hence , slightly pulls the electrons towards itself , and attains partial negative charge , and correspondingly , the hydrogen atom attains partial positive charge .
Hence , from the question ,
The correct option is a.
