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.

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.
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.
What would be some consequences of a nonpolar water molecule?
I am assuming you already know that a water molecule is dipolar, with a slight negative charge due to the negative conductivity of the 2 oxygen atoms in relation to the single hydrogen atom. Adding sodium chloride to the molecule changes its properties further. There are many consequences of this, and it is much too involved to explain in YA.
Why does ethanol is more soluble than methanol?
The OH on the end is slightly negative. Water is polar too, the hydrogens are positive and the oxygen is negative. Because both of the molecules have a net dipole movement (they have positive and negative ends) they attract each other and dissolve each other.
Difference betweend polar and non polar bonds?
Non-polar bonds exist between 2 atoms that have the same electronegativity, which strictly only occurs when both atoms are the same. There is equal sharing of the bonding electron pair. Polar bonds form between 2 atoms that have different electronegativities, and there is unequal sharing of the bonding electron pair. This gives the molecule a permanent electric dipole. This is important in understanding reaction mechanisms as one or other end of the molecule is often attracted to another species, initiating reactions.
Are O3 bonds polar or non-polar?
yes because it is a bent molecule, not linear
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.
Explain the term polar in relation to a water molecule as a whole?
you taking online classes hahaha! im stuck on this question too!

Why is cholesterol non-polar?
well im not 100% sure, but i know that water is polar, and only other polar things can dissolve into it. fats, i.e. cholesterol, are not soluble in water, and therefore must be nonpolar. ALSO, cholesterol is made up of four hydrocarbon rings. hydrocarbon rings, obviously, are made of hydrogen and carbon. (side note - polar compounds are formed when the difference of electromagnetivity - how much the element attracts electrons - between the elements causes an imbalance in the direction of attraction). the difference in electromagnetivity between those two elements is too little to be considered a polar molecule.
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 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.

Is HI a polar molecule?
A molecule's polarity has two main contributing factors: symmetry and bond polarity. In order for a molcule to have poles, it must be asymmetrical and contain polar bonds. In the case of HI, the molecule is asymmetrical, however the difference in the electronegativities between hydrogen (with an electronegativity of 2.1) and iodine (with an electronegativity of 2.5) is technically too small for the H---I bond to be polar. However, there is a characteristic associated with polar molecules called its "dipole moment." The value of a polar molecule's dipole moment can be calculated by multiplying the bond length of the molecule (from nucleus to nucleus) by the charge of the molecules. Since iodine has such a large atomic radius, and therefore a larger bond radius than the hydrogen halides HF, HCl, and HBr, it can be thought of as having a very slight dipole moment. Therefore, HI is a polar molecule.
