Chemistry

Polyvinyl Chloride or PVC is a polymer plastic that is prepared from vinyl chloride (CH2=CHCl).

Nylon 6 : 6  is produced when adipic acid is heated with hexamethylene di-amene in presence of titanium oxide.

After the emission of different volatile compounds as gases by heating coal, the leftover substance is called coke.

If polymer of ethelen (polyethylene) is produced in presence of little oxygen at 200°C temperature and 1200 atm pressure, its density and melting point low and it is soft in nature. This polyethylene is known as LDPE (Low-Density Polyethylene).

The sublevels of an atom are called orbital.

Le Chatelier’s principle states that – if a constraint (such as a change in pressure, temperature, or concentration of a reactant) is applied to a system in equilibrium, the equilibrium will shift so as to tend to counteract the effect of the constraint.

When a group of atoms joins together to form a group that acts like an atom in a chemical reaction, is called a functional group.

The single valence radical formed after removing one hydrogen atom from the Alkane is called Alkyl Radical.
