Water is polar because of the difference in electronegativity between oxygen and hydrogen, and the shape of the molecule. Each H-O bond is polar, and, because of the large, electronegative oxygen atom, the molecule is bent so that the partially negative oxygen atom is at one pole of the molecule and the partially positive hydrogen atoms are at the opposite pole of the molecule.
What else can I help you with?
Is heavy water polar?
Yes, heavy water (D2O) is polar because it contains polar covalent bonds due to the difference in electronegativity between deuterium and oxygen. This causes the molecule to have a slightly positive and slightly negative end, making it polar.
Why is the structure of a water molecule polar?
Since oxygen is more electronegative than hydrogen, you get something called a "dipole moment," making the oxygen slightly negative because of the unequal sharing of electrons. This makes the hydrogen slightly positive since the oxygen atom is more electronegative (I like to think of it as being "hungry for electrons"); the electrons spend more time orbiting the oxygen than they do the hydrogens. Therefore the oxygen is slightly (or delta) negative and the hydrogen, since the electrons spend less time in orbit around the hydrogen, is delta (slightly) positive since an electron has a negative charge. O-H bonds are polar because O and H have different electronegativity values. The vector sum of the two bond dipoles is nonzero. (That is, they are not pointing in exact opposite directions.)
Is distilled water with sucrose polar or nonpolar?
Sucrose is a polar molecule because it has polar covalent bonds due to the electronegativity differences between carbon, hydrogen, and oxygen atoms. When dissolved in distilled water, which is a polar solvent, sucrose will interact with the water molecules through hydrogen bonding, indicating that both the water and sucrose combination is polar.
Why is water considered polar?
Water is considered polar because it has uneven distribution of charge due to the difference in electronegativity between oxygen and hydrogen atoms. This results in a slight negative charge on the oxygen atom and slight positive charge on the hydrogen atoms, making water a polar molecule.
Which is more polar 2-propanol or water?
Water is more polar than 2-propanol because it has a greater difference in electronegativity between oxygen and hydrogen atoms, leading to a larger dipole moment. 2-propanol also has a dipole moment due to the hydroxyl group, but it is less polar than water.
Who is the most polar molecule between HCl and water?
Water is more polar because O has an electronegativity value of 3.5 whereas Cl has value of 3.0
Water is polar or non polar?
Water is polar molecule since oxygen has a higher electronegativity than hydrogen.
Would a molecule with polar covalent bonds be soluble in water?
Yes, in chemistry polar molecules are soluble with other polar molecules. You know that water is polar because of it's structure. Two hydrogens are bonded the an oxygen. The oxygen has two lone pairs of electrons that cause the molecule to have a bent VSEPR structure. This creates a net dipole due to the high electronegativity of oxygen. Essentially, the oxygen is slightly negative and the hydrogens slightly positive. So, yes your polar molecule is soluble with water (also polar).
Is Water non polar?
Water is polar molecule since oxygen has a higher electronegativity than hydrogen.
Is water a polar or nonpolar molecule?
Water is a polar molecule because it has a slight negative charge on the oxygen atom and a slight positive charge on the hydrogen atoms due to differences in electronegativity. This unequal sharing of electrons gives water a polarity, making it a polar molecule.
What is polar substances?

Is heavy water polar?
Yes, heavy water (D2O) is polar because it contains polar covalent bonds due to the difference in electronegativity between deuterium and oxygen. This causes the molecule to have a slightly positive and slightly negative end, making it polar.
Is tap water polar or non polar?
Water is polar molecule. Since oxygen has a higher electronegativity than hydrogen.

Water is considered a polar molecule?
Yes, Hydrogens on one side and the electronegative oxygen at the other.
Is distilled water with sucrose polar or nonpolar?
Sucrose is a polar molecule because it has polar covalent bonds due to the electronegativity differences between carbon, hydrogen, and oxygen atoms. When dissolved in distilled water, which is a polar solvent, sucrose will interact with the water molecules through hydrogen bonding, indicating that both the water and sucrose combination is polar.
Why is there a positive and negative end of the water molecule?
H=O=H Because of oxygen electronegativity being significantly greater than hydrogens electronegativity. The electron shared in this covalent bond are attracted in a stronger fashion to the oxygen and this means they spend more time in the oxygen orbital and then oxygen becomes slightly more negative. By the converse the hydrogens have their two electrons spending more time in the oxygen orbital and thus are slightly positive around their poles. This polar molecule is still considered a neutral molecule over all, but hold a magnet close to water running from a faucet and see the water bend in it's course.
