1
Q

What are the two types of isomerism

A

Structural and geometric

2
Q

State what is meant by structural isomerism

A

A molecule that has the same molecular formula but different spatial arrangements of a atoms or groups

3
Q

What are the three types of structural isomerism

A

Chain
Position
Functional group

4
Q

Give three examples of functional group isomers

A

Alcohols and ethers
Alkenes and cycloalkanes
Aldehydes and ketones

5
Q

State what is meant by a function group isomer

A

Same molecular formula different functional groups

6
Q

State what is meant by the term chain isomer

A

Same molecular formula different arrangement of carbon atoms

7
Q

State what is meant by position isomer

A

Same molecular formula different arrangement of functional groups

8
Q

What is the general formula for alkanes

A

Cnh2n+2

9
Q

What is the general formula for alcohols

A

Cn H2n+1 Oh

10
Q

What is the general formula for an alkene

A

Cn H2n

11
Q

What is meant by the term molecular formula

A

The actual number of atoms in a molecule or element for example

C2H6

12
Q

What is meant by empirical formula

A

The simplest whole number ratio of atoms in a compound for example

CH4

13
Q

How do you name a molecule

A
  1. Highest number of carbon atoms
  2. Look for any functional groups to name the suffix of the
  3. Then number the carbon chain that the functional group is
  4. Make a note of the carbon number the functional group is attached to
  5. Name any side chains
  6. Any side chains less important than functional group at written in alphabetical order
14
Q

Why do we have E/Z isomers

A

Because of restricted rotation of the double bond

15
Q

State what is meant by the term homologous series

A

family of an organic compound with the same functional group and the same general formula
