Water is a "bent" molecule. The angle between the the two O-H bonds is 104 and a half degrees (i.e. well below the 180 degrees that would make it linear). Each O-H bond is polarized. That is, the bonding pair of electrons in each O-H bond is shifted markedly towards the O atom. Each O-H bond thus has a dipole moment. If the molecule was linear, these dipoles would cancel each other out and the molecule would be non-polar. However, there are 2 pairs of non-bonding electrons on the central oxygen atom which are held closer to the O nucleus than are the bonding pairs. These lone pairs of electrons cause more repulsion between each other than do the bonding pairs, which explains why the molecule is bent rather than linear. Because it is bent, the dipoles do not cancel each other out and there is an overall dipole moment vector, meaning that the molecule itself is polar.
What else can I help you with?
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?
No, water is a polar molecule. It has a slight negative charge on the oxygen atom and slight positive charges on the hydrogen atoms due to differences in electronegativity, resulting in a polar overall structure.
What is a molecule that has a partial positive charge on one end and a partial negative charge on the other?
A polar molecule...such as water. The oxygen molecules pulls the electrons closer, causing the oxygen to have a more negative charge and the two hydrogen atoms to have more positive charges. this is very important in the bonding of water molecules to other water molecules.
Is water polar or ionic?
Water is polar due to its bent molecular structure, which causes an uneven distribution of charge. It has a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom, resulting in an overall polar molecule.
Is salicylic acid polar or non-polar?
Oxalic acid is a non-polar molecule due to its molecular structure.
How does the structure of a water molecule affect its properties?
Because the water molecule is bent, it is polar
Why is the structure of water molecule polar?
A water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atoms.
Why is a structure of a molecule polar?
A water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atoms.
how do you explain what polar molecules are?
Water molecules are polar molecules. Both of the bonds inside the molecule are polar bonds.
What happens if water is a polar molecule?
Water IS a polar molecule.
Could Water be a polar molecule?
Water is a polar molecule.
How to know if a substance is a polar or not?
First of all you have to draw the Lewis dot structure of the molecule. If the molecule is symmetrical, it's non-polar. If the molecule is non-symmetrical or asymmetrical, then the molecule is polar.
Is hydrogen phosphate a polar molecule?
Yes, hydrogen phosphate (HPO4^2-) is a polar molecule. It contains both polar covalent bonds and an overall molecular structure that is asymmetrical, leading to an uneven distribution of charge within the molecule.
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 H2O a Polar molecule?
H2O is a water molecule, which is polar.
Is pepsin polar or non polar?
Pepsin is a polar molecule due to the presence of polar peptide bonds in its structure. This allows it to interact with water molecules and other polar substances in its environment.
Is water non-polar?
No, water is a polar molecule. It has a slight negative charge on the oxygen atom and slight positive charges on the hydrogen atoms due to differences in electronegativity, resulting in a polar overall structure.
