Concept explainers
(a)
Interpretation: The complex with higher N-O stretching frequency needs to be identified from
Concept Introduction: In a coordinate complex, a metal is an electron-rich atom which is surrounded by electron-deficient groups known as ligand. Metal donates electrons to the ligand in these complexes. If electron donation from metal to the ligand increases, the stretching vibration between the atom of a ligand which is directly attached to the metal and the atom further attached to it decreases. If the charge on the metal increases, its tendency of donating the electron increases. This decreases the stretching vibration.
(b)
Interpretation: The complex with the longest N-N bond needs to be identified.
Concept Introduction: In a coordinate complex, a metal is an electron-rich atom which is surrounded by electron-deficient groups known as the ligand. Metal donates electrons to the ligand in these complexes. If electron donation from metal to the ligand increases, the bond length between the atom of the ligand which is directly attached to the metal and the atom further attached also increases.
(c)
The complex with shorter Ta-C distance needs to be identified from
Concept Introduction: In a coordinate complex, a metal is an electron-rich atom which is surrounded by electron-deficient groups known as ligand. Metal donates electrons to the ligand in these complexes. If electron donation from metal to the ligand increases, the stretching vibration between the atom of ligand which is directly attached to the metal and the atom further attached to it decreases. If charge on the metal increases, its tendency of donating the electron increases. This decreases the stretching vibration.
(d)
The complex with shorter Cr-C distance needs to be determined from the given complexes. ‘
Concept Introduction: In a coordinate complex, a metal is an electron-rich atom which is surrounded by electron-deficient groups known as ligand. Metal donates electrons to the ligand in these complexes. If electron donation from metal to the ligand increases, the stretching vibration between the atom of ligand which is directly attached to the metal and the atom further attached to it decreases. If charge on the metal increases, its tendency of donating the electron increases. This decreases the stretching vibration.
(e)
Interpretation: The complex with lowest CO stretching frequency needs to be identified.
