CHEM 212 Study Guide - Midterm Guide: Phenyl Group, Protic Solvent, Octet Rule
Document Summary
Stable resonance structures: low charge separation, octet rule, negative on en. Im: ion-ion in ions in crystal lattice; ion-dipole in ions and polar solvents; dd in polar molecules, hb in. Fon (type of strong dd), did in polar molecules and polarizable molecules (large elements and pi systems), dispersion. H-bond donors: hn ho hf, h-bond acceptors: nof. Polar molecules and polarizables (large elements and pi) Have you ever tried to melt salt? ff. Protic = has h-bond donor (usually roh); polar aprotic solvents tend to solvate only cations; polar protic solvents solvate all ions nicely. Alkyl groups: methyl, ethyl, propyl, butyl, isobutyl (all primary); isopropyl, sec-butyl (secondary); tert- butyl (tertiary) Longest continuous chain for basic name with attachment point as c1; identify/number/alphabetize substituents. Func group priority: ha, ye, eth, n, s, ol, one, al, cn, no, est, oxy. Dash goes away from paper because it is disappearing. Eclipsed (are not rotated; one directly behind other) vs staggered.
