the oxygen atom becomes partially negative the hydrogen atom becomes partially positive
Polar. Oxygen's higher electronegativity results in unequal sharing of electrons in the covalent bond with hydrogen, leading to a partial negative charge on oxygen and partial positive charge on hydrogen. This creates a dipole moment in the water molecule, making it polar.
Due 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.

Which molecule will not exhibit hydrogen bonding?
A molecule without hydrogen atoms bonded to highly electronegative atoms, such as nitrogen, oxygen, or fluorine, will not exhibit hydrogen bonding. For example, a molecule like carbon tetrachloride (CCl4) does not have hydrogen bonding capabilities because it lacks hydrogen atoms attached to electronegative atoms.
Is carbon and hydrogen a hydrogen bond in a molecule?
Carbon and hydrogen do not typically form hydrogen bonds with each other in a molecule. Hydrogen bonds form between a hydrogen atom bonded to an electronegative atom (such as oxygen, nitrogen, or fluorine) and another electronegative atom in a different molecule.
Do hydrogen bonds always involve hydrogen?
Yes, hydrogen bonds always involve a hydrogen atom. This type of bond occurs when a hydrogen atom is covalently bonded to a highly electronegative atom such as oxygen, nitrogen, or fluorine, and forms an electrostatic interaction with another electronegative atom.
Can NaF form Hydrogen bonds?
No, NaF (sodium fluoride) cannot form hydrogen bonds because it does not contain hydrogen atoms attached to highly electronegative atoms like fluorine, oxygen, or nitrogen that are necessary for hydrogen bonding. Hydrogen bonding typically occurs between hydrogen atoms bonded to these electronegative atoms and other electronegative atoms in a molecule.
Where can a hydrogen bond form among water molecules?
Hydrogen bonds can form between the hydrogen atom of one water molecule and the oxygen atom of another water molecule. This occurs because oxygen is more electronegative than hydrogen, creating a partial negative charge on the oxygen atom and a partial positive charge on the hydrogen atom, allowing for attraction between these opposite charges.
What is the type of bond that attracts an oxygen and hydrogen molecule?
A hydrogen bond is the type of bond that attracts an oxygen and hydrogen molecule. In a hydrogen bond, the hydrogen atom from one molecule is attracted to the electronegative oxygen atom of another molecule.
Which molecule will not exhibit hydrogen bonding?
A molecule without hydrogen atoms bonded to highly electronegative atoms, such as nitrogen, oxygen, or fluorine, will not exhibit hydrogen bonding. For example, a molecule like carbon tetrachloride (CCl4) does not have hydrogen bonding capabilities because it lacks hydrogen atoms attached to electronegative atoms.
Is water polar because the hydrogens or because the electronegativity?
Water is polar because of the electronegativity difference between oxygen and hydrogen atoms in the water molecule. Oxygen is more electronegative than hydrogen, leading to an uneven distribution of electron density, with oxygen being partially negative and hydrogen being partially positive.
Which element in H20 is more electronegative?
Oxygen is more electronegative than hydrogen in H2O. Oxygen has a stronger pull on electrons due to its higher electronegativity, causing it to attract the shared electrons more strongly in the water molecule.
The hydrogen side of a water molecule is?
The hydrogen side of a water molecule is positively charged. This is because the oxygen atom in water is more electronegative than hydrogen, causing the electrons to be closer to oxygen, leaving the hydrogen atoms with a slight positive charge.
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

Is c5h10 hydrogen bond?
No, C5H10 does not have hydrogen bonds. Hydrogen bonds occur between hydrogen atoms and highly electronegative atoms like oxygen, nitrogen, or fluorine. In C5H10, there are no hydrogen atoms directly bonded to these electronegative atoms to form hydrogen bonds.
How is water a polar molecule?
Water is a polar molecule because it has a bent shape with oxygen being more electronegative than hydrogen, creating an uneven distribution of charge. This results in a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms, making water a polar molecule.
