Isomers

Question 1

Two molecules are isomers of one another if they have …………………………..

Answer 1

• same molecular formula but atoms are arranged differently
• structural formula different

Question 2

Isomers have s……….. c………… p……… but d…………p………..p…………
And why?

Answer 2

Similar chemical properties
Different physical properties : like *boiling points** because of the change in shape of the molecule

Question 3

Can isomers have their functional groups in different places?

Answer 3

Yes
- same carbon atoms arrangement
- same functional group but can be attacked to different carbon atoms
- these isomers have different physical properties

Question 4

Can isomers have different functional groups?

Answer 4

Yes
- same atoms re-arranged into different functional groups
- will have very different physical and chemical properties

Question 5

Explain how isomers can have differently shaped carbon chains?

Answer 5

• carbons arranged differently - straight chain or branched
• will have similar chemical properties but different physical properties (boiling points)
