Q7.
Statement 1: F- ion is weak ligand and forms outer orbital complex.
Statement 2: F- ion can not force the electrons of d z2 and d x2-y2 orbitals to occupy dxy dyz and dzx orbitals of the same shell.
Statement 1: F- ion is weak ligand and forms outer orbital complex.
Statement 2: F- ion can not force the electrons of d z2 and d x2-y2 orbitals to occupy dxy dyz and dzx orbitals of the same shell.
Solution
(a) F^- ion is weak field ligand and it forms outer orbital complex as it cannot force the electrons to pair up.
(a) F^- ion is weak field ligand and it forms outer orbital complex as it cannot force the electrons to pair up.
Q8.
Statement 1: Highly charged cations are expected to form most strongly acidic hydrated cations
Statement 2: The acidity of a hydrated metal ion depends on the strength of the bond between cation and oxygen
Statement 1: Highly charged cations are expected to form most strongly acidic hydrated cations
Statement 2: The acidity of a hydrated metal ion depends on the strength of the bond between cation and oxygen
Solution
(b) Trivalent cations, as a group are more acidic than divalent cations and most monovalent cations have negligible acidic character When cation-oxygen bond is strong, the bond between oxygen and hydrogen is weakened and the proton can be donated to a base
(b) Trivalent cations, as a group are more acidic than divalent cations and most monovalent cations have negligible acidic character When cation-oxygen bond is strong, the bond between oxygen and hydrogen is weakened and the proton can be donated to a base
