Answer 1

Crystalline solids	Amorphous solids
They have long range order i.e there is regular arrangement of molecules over a long distance.	They have short range order i.e there is regular arrangement of molecules over a short distance only.
They are anisotropic i.e the value of physical properties will be different when measured along different directions	They are isotropic i.e they will show same values of all physical properties when measured along different directions
