Definitions Flashcards
Homologus series
A family of compounds with similar chemical properties whos sucessive members differ by the addition of a CH2 group
Functional group
The part of an organic molecules that is largely responsible for the molecules chemical properties
Aliphatic
Carbon atoms are joined to each other in unbranched or branched chains
Alicyclic
Carbon atoms are joined to each other in a ring structure
Aromatic
Contains a benzene ring
Molecular formula
Shows the number and type of atoms of each element in a molecule
Empirical formula
The simplest whole number ratio of the atoms of each element present in a compound
General formula
Is the simplest algebraic formula for any member of a homologus series
Displayed formula
The relative positioning of all the atoms in a molecules and the bonds between them
Structural formula
Shows the arrangement of atoms in a molecule
Structural isomerism
Compounds with the same molecular formula but different structural formulae
Homolytic fission
When a covalent bond breaks by homolytic fission, each of the bonded atoms take on of the shared pair of electrons from the bond
Addition reaction
Two reactions join together to form one product
Substitution
When an atom or a group is replaced by a different atom or a group of atoms
Elimination
Involves the removal of a small molecule from a larger one
Electrophile
Electron pair acceptor
Curly arrow
Shows the movement of a pair of electrons
How we recycle polymers
- processing and sorting polymers by type and recycling
- using waste polymers as fuel for combustion
- use for feedstock recycling
Haloalkanes
Elements of carbon, hydrogen and at least one haloalkane
Nucleophiles
A group or atom which donates a pair of electrons to form a new covalent bond
