The fluorine molecules is formed by : — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Write down the electronic configuration of a Fluorine atom (Z=9): 1s2 2s2 2p5. It has one unpaired electron in a 2p orbital. Step 2: The single covalent bond in F2 is formed by the sharing of these unpaired 2p electrons from two fluorine atoms. Step 3: To form a sigma bond, the two half-filled 2p orbitals overlap along the internuclear axis, which is an end-to-end (axial) p-p orbital overlap, corresponding to option (b).
