For the complex ions
1) $\left.\left[\mathrm{Fe}\left(\mathrm{NH}_3ight)_6ight]^{2+} 2ight)\left[\mathrm{Co}\left(\mathrm{NH}_3ight)_6ight]^{2+}$
3) $\left.\left[\mathrm{Ni}\left(\mathrm{NH}_3ight)_6ight]^{2+} 4ight)\left[\mathrm{Cu}\left(\mathrm{NH}_3ight)_6ight]^{2+}$
5) $\left[\mathrm{Zn}\left(\mathrm{NH}_3ight)_6ight]^{2+}$ the relative stability is in the order\
