Question

what is organic chemistry?

Answer 1

the branch of chemistry that deals with carbon compounds (other than simple salts such as carbonates, oxides, and carbides).

Answer 2

In organic chemistry, main focus is the carbon based material. Carbon is central<building> block of all living organisms; however nonliving things like plastic ,medicine(this r man made)  are made from carbon element. Diamonds are the pure carbon atoms in a crystal structure. Diamonds are so hard it is used in industry for cutting the hard materiel  because the atoms of carbon are so closely bonded together in the crystal form(one of strongest materiel found in nature).
In the modern days v use to build the carbon based structure(layer of carbon) which is stronger and lighter than steel.
