polar covalent
Sulfur dibromide is a bent molecule. In general bent molecules are polar. The situation is a bit complex with SBr2 - when looking at each S-Br bond the difference in electronegativity is small. Bromine is slightly more electronegative than sulfur - so you can think of this bond as either non-polar covalent OR slightly polar. If you draw a vector in the direction of the partial charges (dipoles going from sulfur - to bromine) there will be a very slight polarity. The polarity is very small and since S-Br bonds are typically considered non-polar, many people classify SBr2 as a non-polar molecule since the dipole is very small.
no. it is a non-polar covalent molecule
Elemental sulfur and elemental chlorine are non-polar covalent.
An oxygen molecule has a non polar covalent bond.

The bond in the molecule is covalent.

BeF2 is non-polar as it is (strangely) covalent in nature and as such, the molecule has a linear shape which produces a non-polar molecule.
An oxygen molecule has a non polar covalent bond.
It is called polar
It is a non-polar molecule. But it has polar covalent bonds between its atoms
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.
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.
Carbon dioxide is a non-polar molecule containing polar covalent bonds in its atoms.
