Predicting Hybridization from VSEPR Domain Count

Captions available

The idea

A central atom's hybridization reads directly from its VSEPR domain count: two domains give sp, three give sp², four give sp³, upward.

In practice

Counting sulfur dioxide's three domains, one lone pair and two bonding, predicts sp² hybridization without separately analyzing orbitals.

Where people slip

The domain count from a completed Lewis structure, not the molecule's final named geometry, predicts hybridization.
