Question

Full name of DDT is:
A. $1,1,1 - trichloro - 2,2 - bis(p - chlorophenyl) - ethane$
B. \[1,1 - dichloro - 2,2 - diphenyl{\text{ }}trimethyl{\text{ }}ethane\]
C. \[1,1 - dichloro - 2,2 - diphenyl{\text{ }}trichloroethane\]
D. none of these

Answer 1

Hint:We know that dichlorodiphenyltrichloroethane is commonly known as DDT. DDT is a tasteless, colourless, and odourless crystalline chemical compound, an organochlorine. Originally it was developed as an insecticide. Later, it became infamous due to its environmental impacts. Then, it was first synthesized in 1874 by an Austrian chemist Othmar Zeidler.

Complete step by step answer:
We should remember that DDT (dichloro-diphenyl-trichloroethane) was developed in $1940s$ as the first modern synthetic insecticide. It was initially used with great effect to combat typhus, malaria, and few other insect-borne human diseases among military and civilian populations.
Also, it is effective for insect control in crop and livestock production, homes, institutions, and gardens. DDT's quick success as a pesticide in the United States and other countries have led to the development of resistance with the assistance of many insect pest species. 
DDT is:
-known to be very persistent in the environment,
-will accumulate in fatty tissues, and
-can travel long distances in the upper atmosphere
The structure of DDT is:

According to the structure of DDT, we can write the IUPAC name is $1,1,1 - trichloro - 2,2 - bis(p - chlorophenyl) - ethane$
The correct answer is option A.

Note:
When we speak about DDT, we know that human health gets affected from DDT at low environmental dozes. By following exposure to high doses, human symptoms might include tremors, vomiting, or shakiness, and seizures. Laboratory animal studies showed effects on the liver and reproduction. DDT is considered a possible human carcinogen. DDT was cancelled because it persists within the environment, accumulates in fatty tissues, and may cause adverse health effects on wildlife. In addition, resistance occurs in some insects (like the house fly) that develop the ability to quickly metabolize the DDT.
