When Ag+\mathrm{Ag}^{+}reacts with excess of sodium thiosulphate then the obtained species have charge and geometry respectively

Options

  1. A-3 , linear
  2. B-2, tetrahedral
  3. C-1, square planar
  4. D-3 , square planar.

Correct answer

A. -3 , linear

Step-by-step solution

Ag++2 S2O32−⟶\mathrm{Ag}^{+}+2 \mathrm{~S}_2 \mathrm{O}_3^{2-} \longrightarrow\left[\mathrm{Ag}\left(\mathrm{S}_2 \mathrm{O}_3\right)_2\right]^{3-} Coordination number of Ag+\mathrm{Ag}^{+}is 2 so it has sps p-hybridization and has linear shape.
