What is the shape of ( I ₃⁻ )ion?

Options

  1. ATrigonal
  2. BLinear
  3. CBent
  4. DTrigonal planar

Correct answer

B. Linear

Step-by-step solution

( I ₃⁻ )molecular geometry is linear. While there are three iodine atoms, one of the atoms has a negative charge which further gives 3 lone pairs of electrons and 2 bond pairs. Hence, the correct option is (b).
