Is Br-Br a polar bond

Answer 1

No, it is nonpolar. A polar bond is between two different atoms, which will have different electronegativities (attraction for electrons). The atom with the higher electronegativity will "pull" the shared electrons closer to itself, making that side of the molecule more negative and the other atom's side more positive, creating a polar bond. Two identical atoms will have the same electronegativity and therefore will share the electrons equally, making a nonpolar bond.

Answer 2

Br2 liquid, in its standard elemental condition is non polar. Both Br atoms are equally electronegative and so the covalent electrons are equally distributed between each atom. However, random movement of the electrons can cause temporary instantaneous-induced dipoles on the molecule. This is important in substitution reactions such as electrophilic substitution. The Br2 comes in contact with an electron-dense species and causes one atom of the molecule to become delta + and hence the other becomes delta -. This induced dipole can split the covalent bond between Br atoms leading to a Br- ion and substitute a Br atom into the electron dense species

Answer 3

No, it is NOT polar. The bromine molecule (Br-Br) Br2, is non polar covalent.

Answer 4

The bond is covalent.

Answer 5

nonpolar
