Steric Number and Hybridization Calculation in Organic Chemistry

Steric number is defined within organic chemistry as the summation of sigma bonds and lone pairs associated with a central atom, serving as the primary determinant for calculating atomic hybridization states. This theoretical framework establishes a direct linear relationship between steric numbers ranging from one to six and specific orbital geometries (s, sp, sp², sp³, dsp³, d²sp³), where the exponents of p-orbitals in the hybrid designation explicitly sum with the s-orbital count to equal the calculated steric number.
