4. A water molecule is considered polar because: a) Each atom of a water molecule is amphipathic. b) The hydrogen atoms pull the electrons they each share with the oxygen atom closer to them. c) The electrons shared between the oxygen atom and the each of the two hydrogen atoms are shared unequally. d) The electrons shared between the oxygen atom and the each of the two hydrogen atoms are shared equally. e) The hydrogen atoms donate their electrons to the oxygen atom.
Solution
a) Each atom of a water molecule is amphipathic.,i.e., It has both positive and negative property
One side has positive charge and on other side has negative charge
The hydrogen atom has one electron each
Electrons shared with oxygen atom thus outside of hydrogen willbe positive (polar)
Oxygen has negative charge ultimately
Because of its structure it is called as polar
