hydrocabons - alkenes/cycloalkanes Flashcards
1
Q
how are alkenes different to alkanes?
A
they contain a carbon to carbon double bond somewhere in their structure
2
Q
where can alkenes be found?
A
- plastics
- fuels
- industrial alcohol
3
Q
what is the general formula for alkenes?
A
C n H 2n
4
Q
what is the general formula for cycloalkanes?
A
C n H 2n
5
Q
what are isomers?
A
compounds with the same molecular formula but different structural formula
6
Q
things to remember when determining ismoers?
A
- each alkene has an isomer which is a cycloalkane
- alkenes can form isomers by moving the position of their double bond
7
Q
saturated?
A
contains only carbon to carbon single bonds
8
Q
unsaturated?
A
double carbon to carbon bond
9
Q
alkanes are?
A
saturated as they contain only single bonds
10
Q
alkenes are?
A
unsaturated as they contain a carbon to carbon double bond
11
Q
cycloalkanes are?
A
saturated as they contain only single bonds
12
Q
what is the test for alkenes?
A
alkenes (unsaturated hydrocarbons) decolourise bromine water
