11.2 - Nomenclature of organic compounds

Question 1

Aliphatic

Answer 1

Carbon atoms joining together in either branched or unbranched chains

Question 2

Alicyclic

Answer 2

Carbon atoms joined together to form a ring structure

Question 3

Aromatic

Answer 3

Some/all the carbon atoms join together to form a benzene ring

Question 4

Alkanes

Answer 4

Single carbon-to-carbon bonds

Question 5

Alkenes

Answer 5

Double carbon-to-carbon bonds

Question 6

Alkynes

Answer 6

Triple carbon-to-carbon bonds

Question 7

Prefix

Answer 7

Add before the stem

*indicate the presence of side chains or functional groups

Question 8

Suffix

Answer 8

Add after the stem

*indicate functional groups

Question 9

Naming Aliphatic Alkanes

Answer 9

1. Suffix (-ane)
2. Identify the long carbon chain (parent)
3. Identify side chains to the parent chain (alkyl groups)
   The alkyl group removes the hydrogen atom from the parent chain
   Becomes the prefix to the parent chain
4. Add the numbers before alkyl groups to show the position of the alkyl groups on the parent chain

Question 10

Naming Alicyclic Alkanes

Answer 10

1. Identify the longest carbon chain

2. Prefix (Cyclo-)

Question 11

Naming Alkenes

Answer 11

1. Identify the suffix (-ene)
2. Identify the longest carbon chain
3. Identify double bonds

Question 12

Naming compounds containing functional group

Answer 12

1. Identify the longest carbon chain
2. Identify any functional groups and alkyl side chains and use the correct prefix and suffix
3. Number the alkyl groups according to their position on the longest carbon chain

Question 13

Naming alcohols

Answer 13

1. Identify the functional group and suffix
2. Identify the longest carbon chain
3. Identify which carbon atom has the functional groups

Question 14

Naming Aldehydes

Answer 14

1. Identify functional groups and suffix

2. Identify the longest carbon chain

Question 15

Naming multiple functional group

Answer 15

1. Identify the longest chain carbon

2. Identify the carbon atom the functional group is on and the correct prefix
