  1. Crystalline solids have a definite shape because the atoms are arranged in a geometric pattern while amorphous solid lacks definite shape.
  2. Crystalline solids have very sharp melting points while amorphous solid do not have sharp melting point.
  3. Crystalline solids are anisotropic while amorphous solids are isotropic.
  4. Crystalline solids cleaved in a definite plane while amorphous solid when cleaved they produce fragments that have irregular surfaces.
  5. Examples of crystalline solids are table salt, diamond, sugar etc. Examples of amorphous solids are glass, plastic, coal, rubber etc.

Nitrogen is less reactive at room temperature, P is much reactive, especially white phosphorus is very reactive. The enthalpy of P – P bond is 200 kJ/mol bond. N ≡ N triple bond is much stronger and that’s why the enthalpy is so high. So, to break down P-P bond is much easier than to break N ≡ N bond. Again P4 molecule has a tetrahedral shape and the bond angle is 60°. While N2 molecule is linear and the bond angle is 180°. So, more stress is needed to break N ≡ N bond than P-P bond. So P is much reactive than N.

An aryl group is a functional group derived from a simple aromatic ring compound where one hydrogen atom is removed from the ring. Usually, the aromatic ring is a hydrocarbon. The hydrocarbon name takes the -yl suffix, such as indolyl, thienyl, phenyl, etc. An aryl group is often simply called a "aryl".

Examples: The phenyl functional group (C6H5) is an aryl functional group derived from benzene.
