QUESTION: 9
Which of the following compounds is not coloured?
Solution: It is an inner orbital complex and so does not show d-d transition or any other (like metal to ligand) electronic transition, hence it is colorless.
QUESTION: 10
O2- and Si+4 are isoelectronic ions. If the ionic radius of O2- is 1.4 , the ionic radius of Si+4 will be
Solution: Isoelectronic species: A group of ions, atoms, or molecules that have the same number of electrons.
As the number of electrons in an atom decreases, the effective nuclear charge and attractive force on the outer electrons increases whereas if the number of electrons increases, the effective nuclear charge decreases.Thus, among the isoelectronic species, the one which has more number of electrons has a larger ionic radius and the one which has less number of electrons has a smaller ionic radius.
