Alkenes Flashcards
1
Q
Addition Polymerisation
A
- process
- many identical monomers
- added one at a time
- to form a very long saturated molecule
2
Q
Addition Reaction
A
- reaction where a reactant is added - to an unsaturated molecule
- to make one saturated molecule
- (2 become 1 etc.)
3
Q
Biodegradable
A
- material which is broken down naturally
- by living organisms
4
Q
Carbocation
A
- organic ion
- carbon has a +charge
5
Q
Curly arrow
A
- symbol used in an organic mechanism
- to show the movement of a pair of electrons
6
Q
Electrophile
A
- atom or group of atoms
- accepts a pair of electrons
- to form a new covalent bond
7
Q
Heterolytic fission
A
- breaking of a covalent bond
- both of the bonded electrons going to one atom
- producing a cation (+) and anion (-)
8
Q
Hydration
A
- reaction
- a substance combines with water
9
Q
Monomer
A
- small molecule
- combines many times to form a polymer
10
Q
Pi-bond (π)
A
- reactive part of a double bond
- formed from the sideways overlap of p-orbitals
11
Q
Polymer
A
- long chain molecule
- built up from monomer units
12
Q
Sigma-bond (σ)
A
- covalent bond
- formed by the end to end overlap of orbitals
13
Q
Stereo/Geometric Isomers
A
- Molecules with the same structural formula
- but different arrangement of atoms in space
- (e.g. E/Z and cis-trans)
14
Q
Unsaturated
A
compound containing a C=C bond
