Question

What is the full form of DDT?
A.Dichlorodiphenyltrichloroethane
B.Dichlorodiphenyltrichloroethane
C.Dichlorodiphenyldichloroethylene
D.Chlorodiphenyl Trichloroethylene

Answer 1

We know that DDT is an organochlorine. The structure of DDT is similar to acaricide dicofol and methoxychlor. It is insoluble in water. It is a disruptor of endocrine, and is carcinogen to humans. DDE functions as a weak androgen receptor antagonist.

Complete step by step answer:
DDT is a chemical that is colorless, tasteless, and odorless compound.
The IUPAC name of DDT is 1-chloro-4-[2, 2, 2-trichloro-1-(4-chlorophenyl) ethyl] benzene.
We can draw the structure of DDT as,

We can write the chemical formula of DDT as ${C_{14}}{H_9}C{l_5}.$
DDT is hydrophobic and soluble in organic solvents, oils and fats. However, it is insoluble in water.
We can synthesize DDT from Friedel-Crafts reactions.
Chloral reaction with two equivalents of chlorobenzene in the presence of acid catalyst gives the product as DDT.
We have to know that DDT would gather in fatty tissues, and could travel longer distances in the upper atmosphere.
DDT interferes with the normal nerve impulses and affects the nervous system.
We have to know that DDT is harmful to humans. Humans when exposed to DDT, experience nausea, dizziness, confusion, fatigue, vomiting and tremors.
In insects, it opens a channel of sodium ions present in neurons, making them fire rapidly and leads to immediate death.
The full form of DDT is dichlorodiphenyltrichloroethane.
Hence, the correct option is option A.

Note:
Some of the trade names of DDT are Anofex, Cezarex, Dicophane, Dinocide, Zerdane, Chlorophenothane etc. DDT could be formulated in various forms, such as solutions in xylene or petroleum distillates, aerosols, smoke candles, lotions, water-wettable powders. It is an organic pollutant, which adsorbs oils and sediments.
