Exemple 5: NH3​ Experimentally it is determined that all N−H bonds are equivalent and all H−N−H bond angles are 107.3∘. 9. Show, by writing orbital diagrams for the velmat clectrons of the N atom in its ground and hybrid orbital uates, how it can hybridize to give hytrid orblials whose geomecty is represented by the model (three bonding orbicals plus one lone pair). Electronic configuration for N(2a= ground state hybrid orbicats 10. Now fill in the report able for NH2​, referring to the model you made in rep 7. 11. Remove another white sphere and attached yellow sphere and replace them with a blue sphere representing a second lone pair. What is the geomety of the remaining ap hybrid orbitab? Example 6: H2​O Experimentally is is determined that boch O−H bonds are equivalent and the H−O−H bond angle is 104.5. 12. Show. by writing orbital diagrams for the relmar electrons of the O atom in is ground and hybrid orbital sutes, how s and p orbitals can be combined to give a set of four q2 bybrid orblahs comprising two bonding orbitals and two lone pairs. Electronic configuration of O(Za) ground sute hybrid orbitals 19. Why is the H−O−H angle (104.5r ) less than the H−N−H angle (107.3∘)? 14. Now fill in the repon uble for H2​O.
opld Hybrid Orbitals (Steric Number 5) Atoms of the main-group elements of the third añd following periods can accommodate more than eight electrons around the nucleus-that is, more than four orbitals-because of the availability of vacan 3 d orbitals whose energy is about the same as that of the s and p orbitals in the same period. Construct a model of the 3p3d hybrid orbitals, amanging them as shown below. spid hybrid trigonal bipyramid 1. What atomic orbitals hybridize to give sp3d hybrids? 2. How many spla d hybrid orbitals are formed by hybridization? 5. What is the geometry of the model?
