Question

which has maximum conductivity: a) [Cr(NH3)3 Cl3] b) [Cr(NH3)4Cl2]Cl C)[Cr(NH3)5Cl]2 d)[Cr(NH3)6]Cl3​

Answer 1

d has maximum conductivity

Answer 2

Answer:

The correct answer is Option D : $Cr(NH_3)_6] Cl_3$

Explanation:

The conductivity increases as the number of ions increases.

$[Cr(NH_3)_6] Cl_3$ : Number of ions : $1 + 3$$=4$

$[Cr(NH_3)_3] Cl_3$ : Number of ions : $1$

$[Cr(NH_3)_4Cl_2] Cl$ : Number of ions : $1 + 1 = 2$

$[Cr(NH_3)_5Cl] Cl_2$–Number of ions : $1 + 2 = 3$

Conductivity :

The reciprocal of resistivity, conductivity is a measurement of a substance's ability to conduct electricity.

Hence, the compound which has maximum conductivity among these is Option D : $Cr(NH_3)_6] Cl_3$
