Q

What must you remember when writing organic chemical equations

A

Always use the structural or displayed formula
Never use the molecular formula as it can mean different things

18
Q

What is a reaction mechanism

A

A step by step sequence in which overall chemical change occurs and it outlines the sequence of bonds broken / formed in a chemical reaction

19
Q

What is homolytic fission
When does it usually occur

A

When a bond breaks and each atom gains one of the shared pair of electrons

Usually occurs when the atoms have similar/ the same electronegativities

20
Q

What are free radicals

How are they represented

What products does it form

A

A species with an unpaired electron

By dots

2 free radicals

21
Q

What is heterolytic fission

When does it usually occur

What products does it form

A

When a bond breaks and one atom (the more electronegative one) gains both of the shared pair of electrons

When the atoms have different electronegativities

A free radical and an ion

22
Q

What are curly arrows used to show
How are they drawn

A

The forming and breaking of bonds in mechanisms

Base of arrow is where a pair of electrons is coming from (either centre of bond or lone pair of electrons)

23
Q

How is bond breaking shown in heterolytic fission using curly arrows

A

The curly arrow goes from the centre of the bond

24
Q

How is bond forming shown in heterolytic fission using curly arrows

A

The arrow starts from either a lone pair of electrons or another Covalent bond

25
Q

When do isomers occur

A

When 2 or more compounds have the same molecular formula but a different arrangement of atoms

26
Q

Define structural isomers

A

Isomers with the same structural formula but a different molecular formula

27
Q

What are 3 types of structural isomers

A

Chain isomers

Position isomers

Functional group isomers

28
Q

Define chain isomers

A

When the atoms in the carbon chain are arranged differently

29
Q

Define position isomers

A

Isomers within the same homologous series where the functional group is on a different carbon atom

30
Q

Define functional group isomers

A

When the compounds have the same molecular formula but have different functional groups

31
Q

Define stereoisomerism

A

When the 2 isomers have the same structural formula but with the atoms arranged differently in space

32
Q

What are the conditions for E/Z isomerism in alkenes

A

Each of the carbon atoms either side of the double bond must have different groups of attached to them
