In C2Br4, the central carbon atom is bonded to four bromine atoms. The bond between carbon and bromine is a single covalent bond, formed by the sharing of one pair of electrons between the carbon and bromine atoms. The C-Br bond length is 1.94 Å.

The molecular formula of C2Br4 indicates that there are two carbon atoms and four bromine atoms in the molecule. The two carbon atoms are bonded to each other by a single covalent bond, and each carbon atom is also bonded to two bromine atoms. The bromine atoms are arranged in a tetrahedral shape around each carbon atom.

The C2Br4 molecule is a nonpolar molecule, meaning that it does not have a net electrical charge. This is because the electronegativities of carbon and bromine are very similar, so the electrons in the C-Br bonds are shared equally between the two atoms.
