DDT is used to control certain insects which carries diseases like malaria and yellow fever.
DDT (p,p’-dichloro diphenyl tri-chloro ethane)
DDT, the first chlorinated organic pesticide was prepared in 1873, and in 1939 Paul Muller discovered the effectiveness of DDT as an insecticide. He was awarded Noble prize in medicine and physiology in 1948 for this discovery.
DDT can be prepared by heating a mixture of chlorobenzene with chloral (Trichloro acetaldehyde) in the presence of con.H2SO4.
Uses:
i. DDT is used to control certain insects which carries diseases like malaria and yellow fever
ii. It is used in farms to control some agricultural pests
iii. It is used in building construction as pest control
iv. It is used to kill various insects like housefly and mosquitoes due to its high and specific toxicity.
