Question

2.(a) Explain with diagram, sigma (?) bond and pi (?) bond in terms of number of the bond, overlaps, electron density and freedom of rotation. Using acetaldehyde, CH3CHO as an example, label the bonds as ? or ?. (Focus on central atom that has sigma and pi bond). (b) Based on the Molecular Orbital Theory (MO), explain why the bond dissociation energy for O2+ is higher as compared to the bond dissociation energy of O2. Your answer should include molecular orbital diagrams. (c) Using a square planar compound as an example, explain how you would relate electronegativity to bond polarity and polarity of the whole molecule.

Step 1

Using acetaldehyde; CH₃CHO as an example, label the bonds as σ or π. (Focus on central atom that has sigma and pi bond):** - **Sigma (σ) Bond:** - Number of Bonds: Single bond. - Overlaps: Head-on overlap of atomic orbitals. - Electron Density: Concentrated Show more…
