Bonds in a tetrahedron are 109.5° apart
Carbon-based Chemistry – geometry around Carbon
All single bonds – σ Tetrahedral = sp3
All double bonds – 1 σ, 1 π Trigonal planar = sp2
All triples bonds – 1 σ, 2 π Linear = sp
Lone pairs occupy as much space as bonds
Radicals (single electrons) and empty orbitals do not
Acidity
How do you know which protons “react” (deprotonate)?
Brønsted Acid – proton donor
Brønsted Base – proton acceptor
Lewis Acid – electron acceptor
Lewis Base – electron donor
HA ↔ H+ + A-
