Question

Write the iupac name of [co(nh3)5br ]so4 and write the formula of its ionization isomer.

Answer 1

Pentaaminebrominocobalt[II] Sulphate

Explanation:

• Ionization isomers are identical except for a ligand has exchanged places with an anion or neutral molecule that was originally outside the coordination complex.
• The central ion and the other ligands are identical.

• Since, we have to write the name of the ionisation isomers so in complex [Co(NH3)5Br]SO4, SO4 is counter ions
• thus according to the definition of ionisation isomers SO4 is potential ligand
• so its isomer will be [Co(NH3)5SO4]Br hence, its IUPAC name will be- Pentaaminesulphatocobalt[III] Bromide.
