Vedclass · Answer

(A) $1$. The complex $[Cr(NH_3)_6]Cl_3$ dissociates as $[Cr(NH_3)_6]^{3+} + 3Cl^-$.$2$. $Cr^{3+}$ has an electronic configuration of $[Ar] 3d^3$. It uses two $3d$,one $4s$,and three $4p$ orbitals to form $d^2sp^3$ hybrid orbitals,resulting in an inner orbital octahedral complex.$3$. Since it involves $d^2sp^3$ hybridization,it is an inner orbital complex,not an outer orbital complex. Thus,statement $A$ is incorrect.$4$. It reacts with $AgNO_3$ to give $3$ moles of $AgCl$ (white precipitate),so statement $B$ is correct.$5$. It has $3$ unpaired electrons in the $3d$ subshell,making it paramagnetic,so statement $D$ is correct.

Which of the following statements is incorrect for the complex $[Cr(NH_3)_6]Cl_3$?
