SP2 AND SP HYBRIDIZATION Today we will discuss the formation of Boron trifluoride BF 3 molecule Let’s write the ground state configuration of central atom B and F 5B – 1s2, 2s2, 2p1 9F – 1s2, 2s2, 2p5 B needs 3 unpaired electrons or you can say it needs 3 hybridised orbitals to make bonds with 3 atoms of F

HYBRIDIZATION - Dronacharya
sp2-hybridization: The combination of one s and two p-orbitals to form three hybrid orbitals of equal energy is known as sp2- hybridization Example : BF 3 Molecule
Carbon-Carbon bonds: Hybridization
2 3 Other hybridization orF carbon the most important forms of hybridization are the sp2- and sp3-hybridization Besides these structures there are more possiblities to mix dif-ferent molecular orbitals to a hybrid orbital An important one is the sp-hybridization, where one s- and one p-orbital are mixed together The char-
CHAPTER 14 COVALENT BONDING: ORBITALS
sp2 hybridization The two C−H sigma bonds are formed from overlap of the sp2 hybrid orbitals from carbon with the hydrogen 1s atomic orbitals The double bond between carbon and oxygen consists of one σ and one π bond The oxygen atom, like the carbon atom, also has a trigonal planar arrangement of the electrons that requires sp2

2, determine the hybridization of the oxygen atoms Complete the energy diagram for the oxygens Draw the structure of CO 2 C Each oxygen atom forms 1 sigma bond (with the sp2) and 1 pi bond (with the p) with the sp and p orbitals on the carbon atom energy s p hybridization sp2 p energy s p hybridization sp p energy s p hybridization sp2 p O O
Hybridisation I
