Passage Based Question

Passage

The coordination number of Ni2+ is 4 .

NiCl2+KCN (excess) A (cyano complex) 

NiCl2+ conc. HCl (excess) B (chloro complex)

Show Answer

Solution:

  1. Both statements are true. However, axis of symmetry is not a criteria of optical isomerism. Optical inactivity of the two geometrical isomers of [M(NH3)4Cl2] is due to the presence of plane of symmetry.
