Correctly match is : — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Check the symmetry of atomic and molecular orbitals with respect to center-of-inversion (gerade/ungerade). Gerade (g) means symmetric under inversion; ungerade (u) means asymmetric. Step 2: A sigma-bonding molecular orbital (σ_p_x) is formed by the head-on overlap of p_x orbitals, resulting in a single cylindrical lobe symmetric about the center of the bond. Step 3: Because it remains unchanged upon inversion through the center of symmetry, it is classified as gerade (ψ_g). This makes option (c) the correct match.
