alkanes and haloalkanes Flashcards
haloalkanes
fluoro, bromo, chloro and iodo
higher melting point alkanes
pentane would be stronger than propane because more molecules together
cis and trans application
only to the middle of the molecule
cis isomer
more asymmetrical and polar than the trans isomer
trans isomer
less symmetrical and polar than cis isomer
physical properties of alkenes
non-polar (do not dissolve in water because it is polar)
dissolves in non-polar solvents
boiling points of alkanes and alkenes
alkenes usually have lower boiling points than alkanes
has two fewer hydrogen atoms = slightly weaker LDF
physical properties of alkynes
non-polar (do not dissolve in water but do in non-polar solvents)
boiling points of alkynes and alkane
alkynes have higher boiling point than alkane because the triple bond gives stronger intermolecular force
law of cnservation of mass (LCM)
in a chemical reaction, mass of products = mass of reactants
balancing chemical equations:
M.I.N.H.O
Metals
Ions (polyatomic)
Non-metals
Hydrogen
Oxygen
activity series/ reactivity of single displacement reactions
higher elements on activity series are MORE reactve, can dispace ay element below them, lower elements cannot
exothermic reactions
releasese heat —> gets hot
ex: element +element —> element + HEAT
endothermic reactions
abosorbs heat —-> gets cold
ex: element + heat —-> element + element
burning hydrocarbons
exothermic reaction
