The correct shape and I - I - I bond angles respectively in I 3 - ion are:

Options

  1. AT-shaped; 180 ° and 90 °
  2. BDistorted trigonal planar; 135 ° and 90 °
  3. CTrigonal planar; 120 °
  4. DLinear; 180 °

Correct answer

D. Linear; 180 °

Step-by-step solution

The central iodine atom undergoes sp 3 d hybridization and has 3 lone pairs of electrons and 2 bond pairs of electrons. Thus, I 3 - has trigonal bipyramidal geometry and linear shape . Shape : Linear, I-I-I Bond angle ⇒ 180 °
