Carbon forms tetrahalides with all the halogens.
Carbon also

silicon esters. The
silicon tetrahalides hydrolyse readily in water,
unlike the
carbon tetrahalides,
again because of the

thorium tetrahalides are known, as are some low-valent
bromides and iodides: the

Several anionic technetium halides are known. The
binary tetrahalides can be
converted to the
hexahalides [TcX6]2− (X = F, Cl, Br, I), which...
