test 4
saturation
the measure of amt of bonds carbon has formed w/hydrogen
(higher is more bonds)
ene/yne is less saturated bc of double and triple bonds
what is cyclic
when carbon atoms are arranged in a ring
what does the compound being mor branched mean
lower boiling point as molecules are pushed further apart there is less dispersion force and thus less energy required to break the existing dispersion forces
alkanes use
burning as energy
alkenes use
very reactive so often used in chemistry
alkynes use
good source of energy when oxygen is thrown at it
are compounds with alcohol soluble as alcohol is but the carbon hydrogen bond is not
when smaller chain it is soluble as there is enough solubility to be soluble but when the chain gets larger is becomes less soluble
if the addition group is not on the end of the chain but not in the middle what is it
a secondary bond
less reactive than primary
if the bonded group is in the middle of the chain what is it
tertiary bond
least reactive
alcohol group
OH
carboxylic acid group
COOH
what does a bigger chain with a carbon chain mean
less soluble in polar bc the chain is nonpolar
higher b/mp bc of more dispersion forces so more energy required to break the bonds
what is an ester
a carboxylic acid and an alcohol (wirh H2SO4 as a catalyst)
how to name ester
alcohol and then acid suffix
eg methyl ethanoate
how can an estee be reversed back
hydrolosis
negatives of fossil fuels
finite
CO2/carbon neutreality
greenhouse gases
positives of fossil fuels
cheap/money
theres a lot
the infeastructure is already based around them
