Which of the following statements describe molecules that are structural isomers?

(i) molecules whose atoms have the same arrangement in space

(ii) molecules that have the same molecular formula

(iii) molecules in which the atoms are joined to the same neighbouring atoms

(iv) molecules which the same atoms but they are bonded in a different order

How many functional group isomers of C4H8 are there?

5 / 12

How many functional group isomers of C3H6O2 are there?

It's really difficult to get all of these structures, so don't panic if you miss some. Just spend some time sketching out all the possibilities and remembering some simple rules, e.g carbon forms 4 bonds, oxygen forms 2 etc. Be creative!
