The carbon-carbon double bond in alkenes consists of one strong sigma (σ) bond and one weak pi (π) bond due to head-on overlapping of sp2 hybridized orbitals.
Explanation:
1. Hybridization of carbon atoms: In alkenes, each carbon atom forms three sigma bonds and has one unhybridized p orbital. To accommodate the four sigma bonds, each carbon atom undergoes sp2 hybridization, where one 2s orbital and two 2p orbitals hybridize to form three sp2 hybrid orbitals. The remaining unhybridized p orbital remains perpendicular to the plane formed by the sp2 hybrid orbitals.
2. Formation of sigma bond: The sigma bond is formed due to the head-on overlapping of the sp2 hybridized orbitals. The overlap occurs between one sp2 orbital of each carbon atom, resulting in the formation of a strong sigma bond. This sigma bond allows free rotation around the axis of the bond.
3. Formation of pi bond: The pi bond is formed due to the sideways overlapping of the unhybridized p orbitals. This sideways overlap occurs parallel to the axis of the sigma bond. The overlapping p orbitals form a weak pi bond, which is formed by the interaction of two overlapping p orbitals, one from each carbon atom. The pi bond restricts rotation around the axis of the bond, making alkenes rigid and less reactive than alkanes.
4. Strength of the sigma and pi bonds: The sigma bond formed by the head-on overlapping of sp2 hybridized orbitals is stronger than the pi bond formed by the sideways overlapping of p orbitals. This is because the sigma bond involves a higher degree of overlap and greater electron density between the carbon atoms. Additionally, the sigma bond is formed by the overlap of hybrid orbitals, which are closer in energy and have a better overlap than the unhybridized p orbitals.
In conclusion, the carbon-carbon double bond in alkenes consists of one strong sigma bond formed by the head-on overlapping of sp2 hybridized orbitals and one weak pi bond formed by the sideways overlapping of unhybridized p orbitals.
