Question 1

How do you name a compound?

Answer 1

Identify the longest part of the carbon chain
Identify the functional group
Identify the side chains
Number the chain and make sure you have the lowest number

Question 2

What is the punctuation when naming compounds?

Answer 2

Commas between the numbers
Hyphens between a number and a letter
Successive words are merged into one words

Question 3

What are the rules for naming E-Z isomers?

Answer 3

The group with a higher atomic mass receives priority
E= high priority groups are on opposite sides of the double bond
Z= same side of the double bond

Question 4

What are structural isomers?

Answer 4

Same molecular formula but different structural formula

Question 5

Types of structural isomers?

Answer 5

Chain isomers
Positional isomers
Functional group isomers

Question 6

What is stereoisomerism?

Answer 6

Same molecular formula but different positions in space.

Question 7

What’s geometric isomerism?

Answer 7

Type of stereoisomerism.
Occurs due to restricted rotation of a double bond

Question 8

What’s optical isomerism?

Answer 8

Type of stereoisomerism
Occurs when molecules have a chiral centre- you get a mirror image
