Different types of hybridization, like $sp$, $sp^2$, and $sp^3$, create unique shapes for molecules. This happens because of how the atoms are placed and the angles between their bonds.

1. Types of Hybridization:

   • $sp$: This shape is called linear, with bond angles of $180^\circ$.
   • $sp^2$: This shape is trigonal planar, with bond angles of $120^\circ$.
   • $sp^3$: This shape is tetrahedral, with bond angles of $109.5^\circ$.

2. Lone Pairs Matter:

   • Lone pairs of electrons can change the bond angles. For instance, when there is one lone pair in an $sp^3$ hybridization, the shape turns into a trigonal pyramidal.

3. Electron Pair Repulsion:

   • The VSEPR theory helps us understand that electron pairs try to stay as far apart as possible. This arrangement affects how the molecule is shaped.

So, the hybridization of an atom plays a big role in how its bonds are arranged in three dimensions.
