Isomers

Question 1

What are structural isomers?

Answer 1

Isomers which have the same molecular formula but have a different structural formula

Question 2

What are the three types of structural isomers?

Answer 2

Chain
Position
Functional group

Question 3

What are chain isomers?

Answer 3

They have the same functional groups but different arrangements of the carbon skeleton

Question 4

What are the two types of chain isomers?

Answer 4

Straight chain

Branched chain

Question 5

What are position isomers?

Answer 5

They have the same skeleton and the same atoms or groups of atoms attached but the atoms are attached to different carbon atoms

Question 6

What are functional group isomers?

Answer 6

They have the same atoms arranged into different functional groups

Question 7

What are stereoisomers?

Answer 7

Stereoisomers have the same structural formula but a different arrangement of atoms in space

Question 8

What are the two types of stereoisomers?

Answer 8

E-isomers

Z-isomers

Question 9

Can atoms rotate around a single or double bond?

Answer 9

Single

Question 10

How are the atoms arranged in a E-isomer?

Answer 10

They are opposite sides of the double bond

Question 11

How are the atoms arranged in a Z-isomer?

Answer 11

They are on the same side of the double bond, ie. above or below
