Explanation:Hybridization is a term used in chemistry that defines the orbitals of various atoms based on their paring of electrons. This whole phenomenon takes place according to the valence bond theory. The geometrical shape of [Ni(CN)5]3- is square pyramidal. Its orbitals are s, px, py, pz, dx2 -y2. This molecule has a tendency to crystallize and belongs to point group C4v
dsp2 hybridization and it's shape is of square planar
co or carbon monoxide forms a coordinate covalent bond.
“a coordinate covalent bond” is one of the covalent bond types wherein the electrons are forming the origination of bond from the same atom. coordinate bond forms a central low density area surrounded by one or more areas that have a density of electrons.
co or carbon monoxide forms a coordinate covalent bond. carbon has 6 electrons in the outermost shell whereas oxygen has 8. in a normal molecule, carbon and oxygen will both contribute 2 electrons to the covalent bond to form a double covalent bond. now, 4 electrons are left in the carbon atom and oxygen with 6 to have completed its octet.
carbon is therefore unstable and to gain stability, it now needs to complete its octet and need to gain 2 electrons. carbon cannot contribute electrons because it is already unstable and so oxygen contributes its pair of electrons to form a coordinate covalent bond.
