No, not necessarily. It all depends on the symmetry of the molecule. Take a look at Carbon dioxide. It has a linear shape like this : O=C=O
Although the bonds are obviously polar, the molecule is symmetrical. This makes the polarities of the bonds "cancel" each other, so to speak. So overall, this molecule is non-polar. If you take a look at Hydrogen chloride, on the other hand, it has a shape like this: H-Cl
The molecule is assymmetrical, so this is a polar molecule.
No, if a molecule has both ends that are of the same polarity + or - (no matter how you position it) then the molecule is non polar. There can be polar bonds between atoms in a molecule but that doesn't mean the the molecule overall is polar.
For example, in H2O if you position the molecule so the 2 hydrogen atoms (which are positive) are on one side and the 1 oxygen molecule (-) is on the opposite side, then the overall water molecule is polar because you have a positive end and a negative end. This is an example of a polar molecule with polar bonds.
In the molecule CH4, the carbon atom (in the middle) is negative and all of the hydrogen atoms (which surround the carbon) are positive. But the molecule is still non polar because any way you position the molecule, there will always be a 2 positive sides because of the hydrogen atoms. This is an example of a non polar molecule with polar bonds.
yes, a non polar molecule can have a polar bond, as long as it has another opposite polar bond to counter the first.
No, without polar covalent bonds a molecule can neither be polar.
yes, if a substance dissolves in water, it is said to be polar.
Yes.
If the net dipole moments of the molecules cancel off, then a molecule can have polar bonds and be non polar.
For example
1. CO2, O=C=O.
2. CCl4
No. There are polar molecules and there are nonpolar molecules (as well as amphipathic molecules).
Yes, it is true.
no

polar
Within the molecule, the bonds are covalent bonds. Between water molecules, they're hydrogen bonds.
The molecule is covalent, the N-F bonds are polar covalent.
It is a polar molecule and has polar bonds.
Molecules can be polar or non-polar; bonds are what hold molecules together, but they are not in themselves polar or non-polar. I should point out that the most famous polar molecule in the world, the water molecule, does have covalent bonds.

Water has covalent bonds.The bonds between atoms in a water molecule are covalent bond, somewhat polar ones.

This molecule contains polar covalent bonds.

carbon dioxide
Polar covalent bonds. Not that due to the symmetry of the molecule (tetrahedral) the bond dipoles cancel each other out and overall the molecule is non-polar.
