Addition of excess potassium iodide solution to a solution of mercuric chloride gives the halide complex

Answer»

tetrachedral `K_(2) [HgI_(4)]`
TRIGONAL `K[HgI_(3)]`
linear `Hg_(2)I_(2)`
square planer `K_(2) [HgCI_(2) I_(2)]`

SOLUTION :`HgCl_2 + 4KI to K_2[Hgl_4) + 2KCl`
`Hg : [Xe] 4f^(14) 5D^(10) 6S^(2)`
`Hg^(2+) : [Xe] 4f^(14) 5d^(10) (##MTG_WB_JEE_CHE_C15_E02_005_S01.png" width="80%">
