In water, the two hydrogen's are bonded to the one oxygen. The differing electronegativities make the electrons become shared unevenly. They then become charged positively towards the Hydrogen's (because of less electronegativity) and oxygen charged negatively. This is what makes the bonds polar. The bent shape of the whole molecule makes it so there is more overall negative charge towards the oxygen (because the electrons get attracted more towards the atom with greater electronegativity). This is what makes the molecule polar.
What else can I help you with?
Is caffeine polar nonpolar or ionic Why do you conclude this way?
In fact you can call caffeine both polar and nonpolar, as caffeine (or 1,3,7-trimethylxanthine) consist of both polar and nonpolar components.. On the internet I've seen a lot of people using caffeines ability to disolve in water as an argument for it to be polar.. This is not a good argument though, as caffeine in fact disolves in oils too due to the nonpolarity which I mentioned..
Why chloroform is immiscible with water?
Chloroform (CHCl3), although it is polar, cannot form hydrogen bonds with water and thus the interactions between chloroform and water are too weak to be miscible. In addition, chloroform is significantly heavier than water and will form a bottom layer if mixed.
Is BF3 nonpolar covalent or polar covalent?
No. The individual bonds are polar, but BF3 is trigonal planar so the overall molecule is not polar.
Why is water an excellent solvent for most ionic and polar covalent compounds but not for non polar compound?
Not all ionic salts dissolve in water, just most of them. Anyways, most molecular substances don't dissolve in water because they are more stable not dissolved. This is partly due to the fact that covalent bonds are stronger than ionic bonds. An example of a non-polar substances that can dissolve in water is diatomic fluorine, which when bubbled into water will dissolve.
Why does hydrochloric acid though a covalent compound ionize?
HCl is strictly speaking - a polar covalent molecule with a partial positive charge on hydrogen and a partial negative charge on chlorine. When this is dissolved in water, water too being a polar molecule with a partial positive charge on hydrogen and a partial negative charge on oxygen, hydrogens of HCl are surrounded by oxygens of water forming dipole dipole bonds. So also the chlorines are surrounded by hydrogens of water. When the dipole-dipole bonds are formed, the original bond between H and Cl weakens and ultimately breaks leading to ionization.
Is o-c polar or non polar?
The central oxygen is positively charged, and the molecule is bent at an angle, so it is polar. Since the entire molecule has only oxygens, all bonding is covalent.
Are O3 bonds polar or non-polar?
yes because it is a bent molecule, not linear
Explain the term polar in relation to a water molecule as a whole?
A water molecule is considered polar because it has an uneven distribution of electrons, creating a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom. This polarity allows water molecules to form hydrogen bonds with one another, giving water its unique properties such as high surface tension, cohesive behavior, and solvent capabilities.

No. The individual bonds are polar, but BF3 is trigonal planar so the overall molecule is not polar.
Water molecule is called a polar molecule?
Electrons.Since oxygen is more electronegative, the electrons are more attracted to the oxygen than with hydrogen. So, when the 2 hydrogen are bonded to the oxygen, the oxygen tries to "steal" the electrons. Hence, there are the respective partial positives and negatives.
What is the example polar covalent bonds?
Polarity when one side of a molecule is "more negative" or "More positive" than the other. A covalent bond is when a bond is made of non-metals. Water is polar and is composed of just Hydrogen and Oxygen (which are non-metals). H H O - The "O" (Oxygen molecule) has a slightly negative charge, while the two "H"s (Hydrogen moles) have a slightly positive charge (which I was too lazy to add in.)
Why is cholesterol non-polar?
Cholesterol is non-polar because it is mostly made up of hydrocarbon chains, which contain primarily carbon and hydrogen atoms. These carbon and hydrogen atoms share electrons equally, creating a non-polar structure due to the absence of partial charges.
Why glucose can't make ions?
Because glucose is an organic molecule. Wrong, any molecule or atom can be ionized. Organic or inorganic it does not matter. It just requires enough energy to ionize them. Perhaps you were really asking why it does not ionize in water. This is because all the bonds in glucose are covalent, which is too strong a bond for the dipole charge of the water molecule to separate. To ionize in water a molecule must contain at least one ionic bond, which is weak enough for the dipole charge of the water molecule to easily separate leaving ions. Also there are plenty of organic molecules containing ionic bonds (in addition to many covalent bonds), these readily ionize in water.

Can sugars be dissolved in water?
Yes, sugars like sucrose, glucose, and fructose can easily dissolve in water because they are polar molecules that can form hydrogen bonds with water molecules. These bonds help break down the sugar crystals into individual molecules, allowing them to mix evenly with water.
