Chelation effect is maximum for five and six membered rings

Greater the charge on the central metal cation, greater the value of $△(CFSC)$

In complex ion ${\left[{\mathrm{CoF}}_6\right]}^{3-},F^{-}$is a weak field ligand, so that ${\Delta }_{\text{oct }}<P$ (Pairing energy)and it is low spin complex.

${\left[{\mathrm{CoCl}}_2{\left({\mathrm{NH}}_3\right)}_2(en)\right]}^{\oplus }$ complex ion will have four different isomers.
