Chem 13-3 Flashcards
alkyene + 1 mole H =
alkane
alkyne + 2 moles H =
alkane
propene is also called..
propylene
vicinal dihalide
when 2 halides (Br and Br) are attached to 2 carbons side by side in the products side
solvent with bromine is (bro, clear or chill)
CCl4 or CH2Cl2
it’s usually trans (bro trans)
bromine
with cyclic alkenes, the reaction is usually…
stereospecific, or trans
how to tell if you have a symmetrical alkene just by looking at the formula
CH3 - CH2 - CH = CH2. Look at the hydrogens on either side directly next to the = sign. If they are different, it’s unsymmetrical. The CH = CH2 (above) is unsymmetrical bc it’s 1 hydrogen and 2 hydrogens.
marcovnikov’s law
in unsymmetrical alkene, always add the hydrogen to the carbon w/ more hydrogens, and halogens to the carbon with less hydrogens. rich get richer
ethylene
H2C = CH2 - polyethylene
propylene
H2C = CH - CH3 polyproplyne
vinyl chloride
H2C=CH-Cl poly (vinyl chloride)
styrene (2 stys)
H2C = CH (with benzene attached) polystyrene
styrene
look it up
tetraflouroethylene
F2C=CF2
resonance
the true structure of the molecule can have double bonds in different spots, it’s 50/50. ie - benzene
phenol
benzene w/ OH at side chain
toluene
benzene w/ CH3 at side chain
aniline
benzene w/ NH2 at side chain
naming benzene
1) ortho 2) meta 3) para
ortho - O
side chains at 1 and 2
