Match the following:
Column IColumn II1. Diamondi. Crystalline2. Cokeii. Amorphous3. Rubber4. Plastic
1-(i), 2-(ii), 3-(ii), 4-(ii)
How do we approach this problem??
There are some solids given and we have to figure out whether these are crystalline or amorphous.
So, we have to look at the properties of each compound.
As we already know the properties of crystalline and amorphous.
Diamond → (i) Fixed melting point
(ii) Regular 3-d arranged structure
(iii) Anisotropic
Coke, Rubber, Plastic} → (i) A range of melting point
(ii) Not a regular 3-d arranged structure
(iii) Isotropic
Therefore, Diamond → Crystalline
Coke, Rubber, Plastic } → Amorphous
