Question

course biology #21
multiple - choice question
a polar molecule like water
has similarly charged ends
has oppositely charged ends
is not charged on either end

Explanation:

A polar molecule has regions with opposite charges. For water (\(H_2O\)), the oxygen atom has a partial negative charge (\(\delta -\)) and the hydrogen atoms have partial positive charges (\(\delta +\)). This is due to the difference in electronegativity between oxygen and hydrogen, with oxygen being more electronegative and pulling electron density towards itself. So, a polar molecule like water has oppositely charged ends.

Answer:

has oppositely charged ends
