What are the physical properties of DDT?

What are the physical properties of DDT?

1 Dichlorodiphenyltrichloroethane. DDT is a crystalline chemical compound, which is a colorless, tasteless, hydrophobic, odorless, and low water-soluble compound but shows good solubility in organic solvents, fats, and oils.

Is DDT a solid liquid or gas?

Pure DDT is a colourless crystalline solid that melts at 109 °C (228 °F); the commercial product, which is usually 65 to 80 percent active compound, along with related substances, is an amorphous powder that has a lower melting point. DDT is applied as a dust or by spraying its aqueous suspension.

What chemical properties make DDT an environmental problem?

DDT is very insoluble in water and very persistent in the environment, making it a highly polluting hazard. It’s half life has been reported to be between 2 and 15 years.

How does DDT work chemically?

What is the mechanism of action of DDT? DDT affects the nervous system by interfering with normal nerve impulses (2). DDT causes the nerve cells to repeatedly generate an impulse which accounts for the repetitive body tremors seen in exposed animals (2).

Is DDT flammable?

ICSC 0034 – DDT. Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.

What type of molecule is DDT?

Dichlorodiphenyltrichloroethane, commonly known as DDT, is a colorless, tasteless, and almost odorless crystalline chemical compound, an organochloride. Originally developed as an insecticide, it became infamous for its environmental impacts.

Is DDT volatile?

DDT is highly insoluble in water and is soluble in most organic solvents. It is semi-volatile and can be expected to partition into the atmosphere as a result.

What is DDT and why is it harmful?

DDT is considered to be an endocrine-disrupting chemical, or an EDC, a category of chemicals that researchers find particularly worrisome because of evidence that they alter and disrupt hormones important to good health, including reproductive health, as well as neurological and immune functions.

What is DDT and its uses?

DDT (dichloro-diphenyl-trichloroethane) was developed as the first of the modern synthetic insecticides in the 1940s. It was initially used with great effect to combat malaria, typhus, and the other insect-borne human diseases among both military and civilian populations.

Is DDT lipid soluble?

Since DDT is lipid soluble and accumulates in adipose tissue it could have a role in lipid metabolism.

Does DDT react with water?

Insoluble in water. DDT may react with iron, aluminum, aluminum and iron salts, and alkalis.

Is DDT biodegradable?

Dichlorodiphenyltrichloroethane (DDT) is an organic halogen that acts by disrupting the function of the nervous system, and kills insects rapidly upon contact. DDT is harm to all biota of the planet as it is non-biodegradable, and tends to become more concentrated as it moves up the food chain.

Is DDT polar or non polar?

So, DDT is essentially a nonpolar molecule. We know that Like dissolves like. That is, nonpolar solutes dissolve in nonpolar solvents.

What is the functional group of DDT?

Functional Groups DDT contains choride functional group, phenyl functional group.

Is DDT organic or inorganic?

organic pollutant
DDT is a persistent organic pollutant that is readily adsorbed to soils and sediments, which can act both as sinks and as long-term sources of exposure affecting organisms.

What is chemical name of DDT?

1,1′-(2,2,2-Trichloroethane-1,1-diyl)bis(4-chlorobenzene)DDT / IUPAC ID

Is DDT a polar compound?

Is DDT a greenhouse gas?

DDT is a non-biodegradable pollutant widely used as a modern synthetic insecticide. DDT is an insecticide which is a non-biodegradable pollutant. It is used to kill insects as it acts against insect’s eggs and larvae. The correct option is D, None of the above.
