C=O bonds are polar, but polarity is the uneven distribution of charge ACROSS A MOLECULE, when there is one side slightly negative, and then the other side is slightly negative, the whole molecule is slightly negative, so it's not polar. In other words, the centre of the negative charge is in the same place as the centre of positive charge, and they cancel each other out.
Same story for CCl4, even tho it's not linear, the chlorines are mirror imaged on the other side of the carbon, just like the oxygen is mirror imaged on the other side of the carbon in CO2. The charges are cancelled out, same story for both molecules.
it is an ionic compound so the words ..polar and nonpolar are meaning less....
No. NH3 contains three polar covalent bonds.
Molecules with many polar bonds are soluble in polar solvents.Also, molecules with none or few polar bonds (many non-polar bonds) are soluble in non-polar solvent. e.g Water is a polar solvent so substances with many polar bonds are soluble in it.
nonpolar!
I can't see how.Note that the opposite is a different story: it is possible for a molecule to be nonpolar despite having no bonds that are not polar. For example, consider CCl4, which is nonpolar due to its geometry despite the individual C-Cl bonds each having a substantial polarity.
Yes, a molecule can be nonpolar when it contains polar covalent bonds, because think about it. if the molecule is linear in structure, and it has two equally polar bonds on either side, then the polarity will essentially cancel out, and it will become nonpolar.

strictly polar
nonpolar!
No,bonds are polar.But molecule is non polar.

No, it is non-polar.
Oxygen is an element, not a bond. It will form polar bonds with most other elements, though because it is very electronegative. However, when it bonds with itself as in O2 the bonds are nonpolar.
it is nonpolar since C-H bonds are considered a nonpolar bond
Yes it can
