Chemistry a Central Science
Organic Chemistry
Groups
alkyne
sp, 180*, Linear C(n)H(2n-2)
alcohol
Nucleophilic substitution, oxidation, Beta elimination
Elimination: Zaltsev's Rule: major product has more substituent on alkene
Polar covalent, H bonds
alkene
electrophic addition
Hydrohalogenation: Marovinkov's rule: H adds to the carbon with the most H+'s
Hydrogenation: syn-addition
Halogenation: anti-addition
sp2. 120*, trigonal Planer, Pi and Sigma bonds, C(n) H(2n)
alkane

Terms
mutarutation: hemiacetals sugar open
stereoisomers: enantiomers D and L. Natural form D (OH on right)
anomer difference: shinning polarised light- optical rotation
epimers: stereochemistry different at chiral centre (pentaltimate carbon). D aldose, D glucose
hemiacetals: intermolecular cystalisation that brings the groups (hydroxyl and carbonyl) together
haworth: OH above= Beta, OH below= alpha
Fisher Projections
Chiral Centre at centre cross
most oxided C - Top
Side chain- Bottom
wedged (horizontal bonds)
hatched (vertical bonds)
D when Amino is Right, L when Amino is Left
isomers
constitutional
stereoisomers
enantiomers (R and S): Highest priority 1, lowest priority H-- based off atomic masses. R clockwise, S anti-clockwise
epimers (D and L): DNA and RNA
diastereomers :not mirrored or super impossible
cis/trans (E and Z)
conformers : Newman projections
achiral: super imposable molecule- plane of sym.
Chiral centre: sp3 C atom: bonded to 4 different atoms/groups
