Structure 3.2

Question 1

Naming organic compounds

Answer 1

Named off of the longest C chain and functional groups (position of func group is given from whichever end it is closest to)

Question 2

Naming esters

Answer 2

Use two separate words

Question 3

What groups have the functional group first when naming organic compounds?

Answer 3

Alkyl, halogenalkanes and ethers

Question 4

Empirical formula

Answer 4

Simplest whole number ratio

Question 5

Molecular formula

Answer 5

Shows the actual numbers of atoms present in a molecule

Question 6

Full structural formula

Answer 6

2d representation showing atoms and bonds and their positions relative to one another in the compound

Question 7

Skeletal formula

Answer 7

Representation of the structural formula C and H atoms are not shown but the end of each line and each vertex represent a C atom

Question 8

Hydrocarbons

Answer 8

Compounds that contain only carbon and hydrogen

Question 9

Boiling points of alkanes trend

Answer 9

As n inc so does the bp as the London dispersion forces inc with the inc mass and surface area

Question 10

Structural isomers

Answer 10

Compounds with the same molecular formula but a different arrangement of atoms

Question 11

How to find whether a molecule is primary, secondary or tertiary

Answer 11

how many r groups are attached to it

Question 12

Naming Halgenoalkanes steps

Answer 12

1. Select the largest carbon chain. This is the parent alkane name.
2. Number the chain to give the halogen(s) the lowest possible number.
3. Use the prefix fluoro-, chloro-, bromo-, iodo- in front of the alkane.
4. Put the number(s) in front to identify which carbon of the chain the halogen is attached to.
5. Use the prefixes di (2), tri (3) or tetra (4) if there are more than one of the same halogen.

Question 13

Chain isomers

Answer 13

Differ in the length of the longest C chain

Question 14

Position isomers

Answer 14

Differ in position of the functional groups within the molecule

Question 15

Functional group isomers

Answer 15

Differ in the type of functional group present in the molecule. May have very different chemical and physical properties.
