Solution Steps

Step 1: Determine the Electron Group Geometry
  • Identify the number of electron groups around the central atom in \(\mathrm{ICl}_{2}^{-}\).
  • Iodine (I) is the central atom with two bonded chlorine atoms and three lone pairs.
  • Total electron groups = 2 (bonding pairs) + 3 (lone pairs) = 5.
Step 2: Identify the Electron Geometry
  • With 5 electron groups, the electron geometry is trigonal bipyramidal.
Step 3: Determine the Molecular Geometry
  • The presence of three lone pairs on iodine results in a linear molecular geometry for \(\mathrm{ICl}_{2}^{-}\).
Step 4: Determine the Bond Angle
  • In a linear molecular geometry, the bond angle is \(180^{\circ}\).

Final Answer

The bond angle in \(\mathrm{COH}_{2}\) is \( \boxed{120^{\circ}} \) and the bond angle in \(\mathrm{ICl}_{2}^{-}\) is \( \boxed{180^{\circ}} \).
