AP Chemistry – Class 58

Hybridization

Hybridization

Dates

  • Period E  – Wednesday, January 23rd
  • Period F – Wednesday, January 23rd

Big Idea: Where are the bonding electrons?

Limitations of atomic orbitals

  • geometry of s, p, d, f orbitals?
  • geometry of molecules?
  • compare – do they match? no!
  • need a different system

Bonding Orbitals

  • explains location of electrons in a bonding situation
  • think of as blending atomic orbitals
  • perimeter atoms don’t hybridize

What about multiple bonds?

  • must match geometry with hybridized orbitals
  • count multiple as bonding area
  • extra bonds use left over, unhybridized, “p” orbitals

Overlap

  • along axis = sigma
  • parallel to axis = pi

Examples from Lab

Homework

  • Assign hybridization to all atoms for the examples used during the lab.
