developing fuels- hydrocarbons Flashcards
1
Q
crude oil
A
mixture of hydrocarbons
2
Q
fractionating
A
- seperates different hydrocarbons by heat
- takes place in an oil refinery
3
Q
fractionating column
A
heat gradient
4
Q
different fractions
A
each fraction= made up of hydrocarbons with similar boiling points
5
Q
bubble cap
A
uncondensed hydrocarbons rise through the gaps
6
Q
plates
A
condensed hydrocarbons collect and are taken away by the pipes
7
Q
alkane
A
- all c-c bonds are single
- CnH2n+2
8
Q
alkene
A
- contains at least 1 c=c double bond
- CnH2n
9
Q
arene
A
- unsaturated ring structure
- CnHn
10
Q
cycloalkane
A
- saturated ring structure
- CnH2n
11
Q
carbon chain length
A
- little effect on reactivity
- effects physical properties such as m.p, b.p, solubility
12
Q
aliphatic
A
doesnt contain a benzene ring
13
Q
aromatic
A
contains a benzene ring
14
Q
cyclopropane
A
unstable due to strain
15
Q
naming hydrocarbons- step one
A
find longest chain = backbone. identify & name, e.g. 6 carbons = hexane
