Hybridization for expanded octets Post by Mannat Sukhija 1E » Fri Nov 04, 2016 10:01 pm What would be the hybridization for an atom with an expanded octet, for example the hybridization of P in PCl5?. The hybridization process involves taking atomic orbitals and mixing these into hybrid orbitals. Solution: What is the hybridization of the central atom of each of the following molecules? Match the atoms below with their number---sp, sp2, sp3, sp3d, sp3d2COH2H2SPBr5 Match the atoms below with their number---sp, sp2, sp3, sp3d, sp3d2COH2H2SPBr5. Indicate whether the statements below are true or false. Geometry of PCl 5 based on hybridization: The five sp 3 d hybrid orbitals orient themselves in a trigonal bipyramidal manner, which is the geometry of PCl 5. Hybridization of Orbitals Creating Bonds that are neither pure s nor p nor d! Valence Bond Model Linus Pauling developed valence bond theory/model in the 1930’s and won the Nobel Prize for his work in 1954 A covalent bond is a pair of electrons with opposite spins 1s 2s 2px 2py 2pz F F (in HF) So to form a covalent bond, an atom needs an unpaired electron However, most atoms don’t have. The geometry of PCl 5 is trigonal bipyramidal. Below you will find a quick listing. Total Domains Generic Formula Picture Bonded Atoms Lone Pairs Molecular Shape Electron Geometry. Each equatorial P–Cl bond makes two 90° and two 120° bond angles with the other bonds in the molecule. Hybridization. The Lewis dot structure of PCl3 and PCl5 is given below, Hybridization of P in PCl3 is sp3 because it is surrounded by 4 electron domain (1 lone pair and 3 bond pairs) whereas the hybridization of P in PCl5 is sp3d because it is surrounded by 5 electron domain (5 bond pairs). It has 4 bonding pairs and no lone pairs. Image courtesy:wikipedia.
