1. pπ - dπ bonds are present in SO₂ . 2. SeF₄ and CH₄ have same shape. 3. I₃^+ has bent geometry. 4. PH₅ and BiCl₅ do not exist.

Answer: 2. SeF₄ and CH₄ have same shape. Key idea: compare VSEPR shapes. SO₂ has pπ - dπ bonding: correct. SeF₄ is see-saw (4 bond pairs + 1 lone pair), while CH₄ is tetrahedral. Different shapes, so this statement is wrong. I₃^+ is bent: correct. PH₅ and BiCl₅ do not exist: correct.
