Which bonds are formed by a carbon atom with sp^2-hybridisation? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Carbon in an sp2-hybridized state uses three hybridized orbitals to form three sigma (σ) bonds in a trigonal planar arrangement. Step 2: The remaining unhybridized 2p orbital on Carbon lies perpendicular to this plane and forms one pi (π) bond via lateral overlap. Step 3: Consequently, an sp2-hybridized carbon atom forms exactly 1 pi-bond and 3 sigma-bonds.
