Jahn-Teller effect is not found in high spin complex of -

Jahn - Teller effect is not observed in high spin complexes of a. d^(7) b. d^(8) c. d^(4) d. d^(9)

Jahn-Teller effect is predominantly observed in low spin complexes having configuration

C_(6)H_(5)C-=N and C_(6)H_(5)N-=C exhibit which type of isomerism

C_(6)H_(5)CHO+HCNrarrC_(6)H_(5)CH(CN)OH The product would be

C_(6)H_(5)CHO + HCN rarr C_(6)H_(5)CH(CN)OH . The product would be

Explain the following giving reasons (a) [NiCI_(4)]^(2-) is tetrahedral and paramagnetic whereas [Ni(CN)_(4)]^(2-) is square plannar and dimagnetic (b) [Fe(H_(2)O)_(6)]^(3+) ion is more paramagnetic than [Fe(CN)_(6)]^(3-) ion (c ) Ni(CO)_(4) is tetrahedral while [Ni(CN)_(4)]^(2-) ion is square planar (d) [Co(F_(6))]^(3-) is a high spin complex whereas [Co(CN)_(6)]^(3-) ion is a low spin complex .

[Fe(CN)_6 ]^-3 is low spin complex but [Fe(H_2O)6]+3is high spin complex. Explain.

C_(6)H_(5)N_(2)Cl + CuCN to C_(6)H_(5)CN + N_(2) + CuCl is
