and 
show different colour in dilute solutions because
A
is a strong field ligand and 
is a weak filed ligand hence magnitude of CFSE is different
B
Both 
and 
absorb same wavelength of energy
and absorb same wavelength of energy
C
Complexes of weak filed ligands are generally colourless
D
The sizes of 
and 
are different hence their colour are also different.
and are different hence their colour are also different.
Text Solution
Verified by ExpertsThe correct answer is:
A
is a strong field ligand hence pairing of electrons takes place while in case of 
pairing does not take place. Both ligands show different magnitude of crystal field splitting energy hence absorb different wavelengths and show different colurs.
