Structure of the complex with `sp^3` hybridisation

Write a few sentences about sp hybridisation ?

Assertion: The number of unpaired electrons present in [CuCl_2]^(-) complex is zero Reason: The complex is linear in the solid state with sp- hybridization

Assertion: The spin only magnetic moment of [MnBr_4]^(2-) is 5.9 BM Reason: [MnBr_4]^(2-) is tetrahedral with sp^3 hybridisation of Mn^(2+) having 3d^5 configuration

Alkyl free radicals are planar and the central carbon atom is in sp^(2) hybridisation

The negatively charged carbon atom in the carbanion is in sp^(3) hybridisation. Its shape is pyramidal or tetrahedral with one lone pair

In which of the following pairs of molecules/ ions, the central atoms have sp^(2) hybridisation?

The d-orbitals participating in hybridisation of metal atom may be from the n & (n-1) shell. This depends on the nature of metal and nature of ligand. The complexes involving the inner d-level (inner orbital complexes) results when the ligand is a powerful (or) strong ligand results in a diamagnetic (or) low spin complexes. A weak ligand usually results in the formation of outer orbital complex (or) high spin complex. The hybridisation of Cu in [CuCl_(4)]^(2-)&[Cu(NH_(3))_(4)]^(2+) are respectivly

Which of the following complex species does not involve d^2sp^3 hybridisation?

Which of the following compounds are formed by sp^3d hybridisation
