1)Carboxylic acid containing one carbon atom is called........
2)............... Is the ionic part of synthetic detergent.
3) what are diamond and graphite

1) Carboxylic acid containing one carbon atom is called methanoic acid (HCOOH) . 
2) Detergents are sodium salts of long chain benzene sulphonic acids. The ionic group in soaps is SO3 Na+ or SO4 -Na+
3) Both diamond and graphite are allotropes of carbon. That is, they are entirely composed of the element carbon and so will be represented by the symbol for carbon i.e. C.  
Diamond and graphite can be differentiated from each other in the following manner.
 
Diamond
Graphite
It is the hardest mineral known. It is one of the softest mineral. It is soft and slippery.
Carbon bonded to four different carbon atoms forming tetrahedron.
 
Each carbon atom is joined to three other carbon atoms by strong covalent bonds to form flat hexagonal rings.
Tetrahedrons combine to form a rigid 3-D structure.
 
Has 2-D layer-like hexagonal structure.
 
Does not conduct electricity
 
Good conductor of electricity
