What is halogenated hydrocarbons?

Question

what is the structure of halogenated hydrocarbon?
what is its possible hazards to our environment?

Answer 1

An aliphatic or aromatic hydrocarbon in which one or more hydrogen atoms are substituted by halogen.

Answer 2

Freons are not the only halogenated hydrocarbons, nor refrigeration their only use. Freons are also used for fire-suppression in computer rooms & around sensitive equipment.

For decades, the degreaser perchlorethylene was widely used to clean grease & oil from metal parts until its carcinogenicity was established. 1,1,1 trichlorethane is still used as a degreaser, being somewhat less strongly carcinogenic as perc. Chloroform was used as an anesthetic after its numbing properties were noticed by a young doctor in the 1800s at a chloroform party, where young people would gather together & take hits off the chloroform (I am not making this up). Until ether was discovered,
chloroform was the first "modern" anesthetic. Like all chlorinated hydrocarbons, it is hard on the liver & kidneys.

Until consumer concerns caused cofee companies to start using other processes, dichloromethane was at one time the solvent with which caffeine was removed to create decaffinated coffee.

The most widely used class of halogenated hydrocarbons is probably pesticides. Not just the famous & banned DDT, but the closest can of RAID has chlorpyrifos or some other chlorinated hydrocarbon as its active ingredient. Ditto for the banned & highly toxic weedkiller Silvex.

And we shouldn't leave out the synthetic sweetener SPLENDA.
Look up its formula. You may think twice about consuming it with the illustrious company it keeps in the chemical world.

Answer 3

A Halogenated hydrocarbon has one or more of the hydrogen atoms replaced by a halogen atom. Halogens are elements such as Chlorine, Flourine, Bromine, and a couple of others.

Structural formula of isoflurane, a typical halogenated ether. The C-O-C (carbon-oxygen-carbon) in the center is the ether group and the Cl (chlorine) and F (fluorine) are the halogen atoms, which have been substituted for all but two H (hydrogen) atoms.A halogenated ether is a subcategory of a larger group of chemicals known as ethers.

Environmentally these compounds are thought to cause damage to the ozone layer and have been outlawed by most countries.

Answer 4

R(X)n where R is hydrocarbon chain and X is halogen atom and n is the number of halogen atoms.

Risk of damage of ozone layer protecting earth from cosmic radiation.
