19
Q

Molecular formulae

A

No type of atoms present
Does not show bonding
Isomers

20
Q

Empirical formulae

A

Simplest whole no ratio of atoms

Homologous molecules have same empirical formulae

21
Q

General formulae

A

Simplest algebraic formula for any homologous series

22
Q

General formula of alkanes

A

Cn H2n+2

23
Q

General formula of alkenes

A

Cn H2n

24
Q

General formula of alcohols

A

Cn H2n+1 OH

25
Q

General formula of carboxylic acids

A

Cn H2n O2

26
Q

General formula of ketones

A

Cn H2n O

27
Q

Displayed formula

A

Relative positioning of all atoms in a molecule and bonds

28
Q

Structural formula

A

Smallest detail necessary to show arrangement

Shows bonds

29
Q

Skeletal formula

A

Remove all C and H

Molecules with functional groups must be included

30
Q

Structural position isomers

A

Same molecular formula, different structural formula
Draw out the different ways that the carbons can be joined
If functional group present, place in different positions

31
Q

Functional group isomers

A

Same molecular formula, different functional group

32
Q

Types of bond fission

A

Homolytic fission

Heterocyclic fission

33
Q

Homolytic fission

A

Each bonded atom takes one of the shared pair of electrons from bond
Each atom now has a single unpaired electron, radical

34
Q

Heterolytic fission

A

One bonded atom takes both electrons from bond

Anions, cations formed

35
Q

Reaction mechanisms

A

Curly arrows, heterolytic fission

Fish hook arrows, homolytic fission

36
Q

Addition reactions

A

2 reactants join, form 1 product

37
Q

Substitution reactions

A

Atom/groups of atoms replaced by different atoms

38
Q

Elimination reactions

A

Removal of molecule from larger one
