alkanes Flashcards
what are hydrocarbons?
organic compounds made of carbon and hydrogen
most of the molecules in hydrocarbons are?..
alkanes.
in alkanes what do carbon atoms bond to?
four other atoms (hydrogen or carbon)
why do we call these saturated hydrocarbons?
because they only contain single bonds with other atoms/
are alkanes reactive.
no they’re quite unreactive.
true or false- alkanes can burn WELL
true
why are alkanes useful fuels?
because they can burn well.
whats the general formula for alkanes?
CnH(2n+2)
if a hydrocarbon contained 7 carbon atoms what would the number of hydrogen atoms be
(2x7)+2=16
what would the formula for a hydrocarbon w 7 carbon atoms be?
C7H16
if an alkane contains 21 carbon atoms its formula would be
C21H44.
this is because->
2n+2=(2x21)+2=44
4 smallest alkanes in ascending order-
methane (CH4)
ethane (C2H6)
propane (C3H8)
butane (C4H10)
what are the three last letters in all alkanes?
-ane
