Chemical Bonds and Lewis SymbolsThursday, 21 April 20167:24 PMLewis Structures Give atomic connectivity, physical connection betw atoms 2 atoms/ions strongly attached = chemical bond (3 types) Ionic bond: Electrostatic force betw ions of opp charge Covalent bond: sharing of electrons Metallic bond: Each atom - neighbouring atoms. E- relatively free tomove Not for metallic bonds Covalent bonds - Lewis symbols Each pair e- in bond = single lineOctet Rule All noble gases ex He = s2p6 configuration Atoms = gain, lose, share e- until surrounded by 8 valence e- (4 epairs) Many exceptionsMultiple Bonds More than 1 pr e- shared betw 2 atomso 1 shared pr = single bondo 2 shared pr = double bondo 3 shared pr = triple bond Bond distance dec. single => double => triple bondsResonance StructuresElectrons shift in order to find most stable position within molecule Some molecules not well described by Lewis structures Structures w/ multiple bonds can have similar structures w/ themultiple bonds betw diff prs atoms e.g. experimentally, ozone = 2identical bonds, but Lewis Structure = 1 single (longer) and 1 double(shorter) Hence, RS = attempt to represent real structure that is a mix betwseveral extreme possibilities Benzene = aromatic compound NB lone pair of electrons must be next to pi bond in order to form RSFormal Charge = (#VE in free atom) - (#VE in bonded atom) - It's goodto have structure
