Extended structure

Question 7

Structure of atoms or molecules in a 3D pattern

Answer 7

Crystal

Question 8

Structure of molecules with a repeating chain pattern

Answer 8

Polymer

Question 9

Glucose and fructose both have an atomic composition of C6H12O6 but they are different molecules. What is most likely the major difference between them?

Answer 9

They have a different chemical structure

Question 10

List 2 differences between crystals and polymers. Hint: one is shape and one is composition.

Answer 10

Polymers are chains and crystals are a 3D pattern. Crystals can be atoms or molecules but polymers can only be molecules.
