What is the molecular shape of OCl? bent square planar linear see-saw tetrahedral The Correct Answer and Explanation is: The molecular shape of OCl₂ (oxygen dichloride) is bent. Here’s a detailed explanation: To determine the molecular shape of OCl₂, we use the VSEPR (Valence Shell Electron Pair Repulsion) theory. VSEPR theory states that the electron

The molecular shape of OCl2 A. None of the above B tetrahedral C. Bent D. Triagonal planar e. Linear The Correct Answer and Explanation is: The correct answer is C. Bent. Explanation: OCl₂ (oxygen dichloride) is a molecule that consists of an oxygen (O) atom bonded to two chlorine (Cl) atoms. To determine its molecular
