Answer:
Sucrose. Option 4 is correct.
Explanation:
Crystallinity can be defined as the degree of structural order in a solid.
Let us take a look at each of the material mentioned in the question..
The first one is WATER. Water has the molecular formula of H2O, it is bent at an angle approximately 104.5 degrees. Because of its molecular form as liquid, WATER is amorphous and NOT crystalline.
The second material is GLASS: GLASS do not crystallized when they become hardened.
The third material is Nitrogen, NITROGEN is a non metallic element of group 15. Although solid nitrogen have crystalline modifications, they still exist as amorphous.
The fourth material is sucrose. SUCROSE is a disaccharide. It is a crystalline white solid.
