Question

Discuss the structure of [NiCl⁴]²- with the help of Valence Bond

Theory (VBT)​

Answer 1

Explanation:

The central metal ion present in this complex isNi2+

. Atomic number of Nickel is 28. Electronic configuration is Ni is [Ar]3d 8 4S 2

. Electronic configuration is Ni +2

is [Ar]3d 8 4S 0

. Nickel is sp 3

hybridised which results in tetrahedral geometry. Two unpaired electrons are present. Hence, the complex ion is paramagnetic.

Answer 2

Explanation:

The central metal ion present in this complex is Ni2+

. Atomic number of Nickel is 28. Electronic configuration is Ni is [Ar]3d8 4S2

. Electronic configuration is Ni +2

is [Ar]3d84S0

. Nickel is sp3

hybridised which results in tetrahedral geometry. Two unpaired electrons are present. Hence, the complex ion is paramagnetic.
