Tardigrade Admin · Accepted Answer

i) It contain negative ligands only

ii) The oxidation state of central metal atom is +3

iii) It is optically active

iv) Due to chelation the stability of the complex increases

v) It is an octahedral with

d^{2} s p^{3}

hybridization.

the above statement are correct.

i) It contain negative ligands only ii) The oxidation state of central metal atom is +3 iii) It is optically active iv) Due to chelation the stability of the complex increases v) It is an octahedral with d2sp3 hybridization. the above statement are correct.

i) It contain negative ligands only

ii) The oxidation state of central metal atom is +3

iii) It is optically active

iv) Due to chelation the stability of the complex increases

v) It is an octahedral with $d^{2} s p^{3}$ hybridization.

the above statement are correct.
