Detrital- made of sediment grains
Orgains- Made of fossils
Chemical- from due to chemical reactions
I hope this helped you enough :)
Detrital rocks are composed of rock particles, chemical sedimentary rocks are composed of precipitated minerals.

It can be. Some limestone is formed from the precipitation of calcite from saturated solutions, and is considered a chemical sedimentary rock. Other limestone that consists largely of the skeletal remains of marine organisms is considered bio-clastic, a cross between an organic and a detrital sedimentary rock. Typical detrital sedimentary rocks are those composed mostly of particles of pre-existing rock, although organic matter may be included; examples would be sandstone, shale, and conglomerate.
Organic sedimentary rocks are formed from the remains of plant and animal life. Chemical sedimentary rocks are formed from the precipitation of minerals in a solution.
Chemical sedimentary rocks precipitate from solution. Organic is a subsection of chemical and includes limestone and coal, detrital, or clastic, are detritus, or fragments, of other rocks (e.g., sandstone). ChaCha on!
A sedimentary organic rock is living or was once living like a coral. Chemical is chemically made and is usually man cut.
1) Chemical and biological sedimentary rocks are produced by chemical weathering instead of the siliciclastic sediments which are created by physical weathering. Because physical weathering is much more often than the chemical weathering there are 10 times more clastic sediments in the earth's crust than chemical and biological sediments.
Clastic: These rocks are composed predominantly of broken pieces of older weathered and eroded rocks Non-clastic/ Organic: A sedimentary rock composed of the remains of plants and animals.
To put it simply, 'clastic' means that the sedimentary rock is deposited from 'recycled' previous rock, 'organic' means that it is sedimentary rock derived from some form of life - plants or animals, and 'chemical' means that it has precipitated out of water through evaporation or through chemical interaction of two different bodies of water.
The chemical sedimentary rock will not be composed of cemented rock particles.
