Because oxygen is more electronegative than hydrogen the water molecule is what?

∙ 14y agoDue to the difference in electro-negativities between the oxygen and hydrogen the bonding between the two atoms is polar covalent. This means an unequal sharing of the electrons. The oxygen is more electronegative so hence it is more greedy in pulling the shared electrons between the atoms closer to itself. This leaves the hydrogen atoms in water slightly electron deficient whilst the oxygen is electron rich. The result is an overall dipole moment in water. one can consider each bond to have a dipole moment and as such to act as a connection point to associate with other dipoles (water molecules). The association of different water molecules through the dipoles is often called hydrogen bonding and this can result in a multitude of structures from chains to tetrahedral arrangements. This unique property is responsible for the higher than expected boiling/melting point of water as well as the expansion in volume of ice and hence the lower density of ice relative to liquid water.

Do hydrogen bonds always involve hydrogen?
As far as I know: yes! They involve hydrogen bonded to an electronegative element (like oxygen). This Hydrogen in the molecule is then attracted to another electronegative element (like oxygen, nitrogen etc)
True or false Water is an example of a polar molecule?
True. Water is slightly negative on the oxygen end and slightly positive on the hydrogen's end of the molecule. This is because oxygen is much more electronegative than hydrogen, so the electrons in the covalent bond spend more time around the oxygen.
Why is water a polar molecule?
The water is a polar molecule because it is not equally charged. Its half side has a positive charge and the other half has a negative charge. because the electrons spend more of their time with the oxygen and not with hydrogen and due to this they get more negative charge and due to this the water is a polar molecule.---------------------------------------------------------------1. The water molecule is not linear.2. Oxygen is more electronegative than hydrogen.3. As a consequence the hydrogen atoms are slightly positive and the molecule is polar.
Why dont hydrogen and oxygen atoms share electrons equally in a water molecule?
Because the electronegativity of oxygen is about 3.5 and the electronegativity of hydrogen is about 2.5. So, the electrons shared in this polar covalent bond spend more time in the orbitals around oxygen that the orbitals around hydrogen giving the molecule slightly negative and positive ends.
What explain is negative charge on the oxygen atom within the water molecule?
Oxygen atoms are highly electronegative and pull electrons away from the electropositive hydrogen atom.
Water is a polar molecule because?
Oxygen is more electronegative than hydrogen and creates a dipole moment.
Do hydrogen bonds always involve hydrogen?
As far as I know: yes! They involve hydrogen bonded to an electronegative element (like oxygen). This Hydrogen in the molecule is then attracted to another electronegative element (like oxygen, nitrogen etc)
Is water polar because the hydrogens or because the electronegativity?
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.
The attraction of water particles to each other?
Strong hydrogen bonds as the Oxygen is really electronegative and the hydrogen is really unelectronegative. The hydrogen bonds to the oxygen of another molecule.
Is c5h10 hydrogen bond?
No. In order for hydrogen bonds to form, hydrogen must be bonded to a highly electronegative element such as oxygen, nitrogen, or fluorine. In this molecule it is only bonded to carbon, which is not electronegative enough.
What type of bond is formed between a hydrogen on one polar molecule and a very electronegative atom such as oxygen or nitrogen on another polar molecule?
a hydrogen bond
What causes the water molecule to have a negative charge?
The water molecule does not have a negative charge. The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge. This is because the oxygen atom is more electronegative than the hydrogen atoms, and tends to hold the shared electrons more tightly than the hydrogen atoms.
Which element in H20 is more electronegative?
Oxygen is more electronegative than hydrogen.
What is a polar molecule which has a slighty negative charge near the element?
Water is a common example of a polar molecule. A molecule is polar when the electrons tend to spend more time around one area than others. This happens when atoms on one side of the molecule are more electronegative than the others. (Atoms that are higher and farther to the right on the periodic table are more electronegative.)Water is polar because both hydrogens are on one side of the oxygen, and hydrogen is more electronegative than oxygen. Because of this, the hydrogen side is partially negative, while the oxygen side is partially positive.
True or false Water is an example of a polar molecule?
True. Water is slightly negative on the oxygen end and slightly positive on the hydrogen's end of the molecule. This is because oxygen is much more electronegative than hydrogen, so the electrons in the covalent bond spend more time around the oxygen.
When hydrogen is attached to the more highly electronegative oxygen atom in a water molecule?
When hydrogen is attached to a more electronegative element, the electronegative atom becomes partially negative and the hydrogen atom becomes partially positive
Why is water a considered a polar molecule?
Because oxygen is slightly more electronegative than hydrogen and when those 2 particles bond together electrones are more likely to be closer to oxygen. This results with oxygen having negative charge and hydrogen having possitive charge, thus water is a polar molecule.
