Question

Consider the coordination compound, [Co(NH3)6]Cl3. In the formation of this complex, the species which acts as the Lewis acid is : (A) [Co(NH3)6]3+ (B) Cl- (C) Co3+ (D) NH3

Metalcation i.e. Ca3+ act as a lew is acid which accept lone pair from ligands of NH3.

Q. Consider the coordination compound, $[C o (N H_{3})_{6}] C l_{3}$ . In the formation of this complex, the species which acts as the Lewis acid is :

$[C o (N H_{3})_{6}]^{3 +}$

$C l^{-}$

$C o^{3 +}$

$N H_{3}$

Metalcation i.e. $C a^{3 +}$ act as a lew is acid which accept lone pair from ligands of $N H_{3} .$
