What is the difference between 1 1 dichloroethane and 1/2-dichloroethane?
Hint: The only difference between 1,1-dichloroethane and 1,2-dichloroethane is that the two chlorine atoms are present on the same carbon atom in case of 1,1-dichloroethane, they are present in the adjacent carbon atoms in case of 1,2-dichloroethane.

What type of isomerism is shown by 1 2-dichloroethane?
cis-trans
1,2 – dichloroethene shows cis-trans or geometrical isomerism.
Why was trichloroethane discontinued?
Fatal poisonings and illnesses linked to intentional inhalation of trichloroethane have been reported. The removal of the chemical from correction fluid commenced due to Proposition 65 declaring it hazardous and toxic.
Is EDC flammable?
Ethylene Dichloride (EDC) or 1,2-Dichloroethane is a clear, flammable liquid. Its chemical formula is C2H4Cl2. Although the vast majority of common chlorinated compounds are non- flammable, EDC has a flash point of 13°C (55.4°F). Since EDC is a flammable liquid, it must be stored and handled with this hazard in mind.
Is ethylene dichloride toxic?
The Occupational Safety and Health Administration (OSHA) has classified ethylene dichloride as toxic, flammable, and carcinogenic (having the potential to cause cancer.) It can be dangerous to humans if it is inhaled, swallowed, or comes into contact with the skin.
Is dichloroethane a carcinogen?
The U.S. Environmental Protection Agency (EPA) has classified 1,2-dichloroethane as a probable human carcinogen. The International Agency for Research on Cancer (IARC) has determined that 1,2-dichloroethane is possibly carcinogenic to humans.
When 1,1-dichloroethane is boiled with aqueous KOH The product obtained is?
ethanol
1,1-Dichloroethane reacts with aqueous KOH to give ethanol.
What type of isomerism is shown by 1,2-dichloroethane?
Does 1/2 dichloroethane have isomers?
There are two isomers of 1,2-dichloroethene, the cis form and the trans form.
What is the structure of 1/2 dichloroethane?
C2H4Cl21,2-Dichloroethane / Formula
Is trichloroethylene still used?
TCE is widely used in industry. It was mainly used for degreasing manufactured metal parts. TCE has been replaced by other solvents for some degreasing operations, but millions of pounds are still used annually.
Is trichloroethylene banned in the US?
In June 2018, EPA abandoned the proposed bans altogether and decided to fold those high-risk uses into a new risk evaluation of TCE—a move that is delaying action for years with no assurance those dangerous uses will be banned in the end.
Is EDC heavier than air?
Chemical Identity
The liquid is heavier than water. EDC evaporates readily at ambient temperatures. It has a sweet odor typical of chlorinated hydrocarbons. The vapors are heavier than air and tend to sink to low areas.
Is ethylene dichloride cancerous?
Cancer & Ethylene Dichloride
The EPA lists ethylene dichloride as a Group B2 carcinogen. This means it is “probably carcinogenic to humans,” based on sufficient evidence from animal exposure but limited evidence from human exposure. This classification is based on both inhalation and ingestion.
Is ethylene dichloride harmful to humans?
Inhalation of concentrated ethylene dichloride vapor can induce effects on the human nervous system, liver, and kidneys, as well as respiratory distress, cardiac arrhythmia, nausea, and vomiting. Chronic (long-term) inhalation exposure to ethylene dichloride produced effects on the liver and kidneys in animals.
What is the boiling point of EDC?
182.2°F (83.47°C)1,2-Dichloroethane / Boiling point
What happens when 1-dichloroethane is heated with aqueous KOH?
1,1-Dichloroethane reacts with aqueous KOH to give ethanol.
What happens when 1/2 dibromoethane reacts with excess alcohol KOH?
When 1,2-dibromoethane (ethylene bromide) is boiled with alcoholic potassium hydroxide, ethyne is formed.
Can 1/2 dichloroethane show geometrical isomerism?
1,2 – dichloroethene shows cis-trans or geometrical isomerism.
Is dichloroethane a polar molecule?
1,2-dichloroethane is a member of the class of chloroethanes substituted by two chloro groups at positions 1 and 2. It has a role as a non-polar solvent, a hepatotoxic agent and a mutagen.
Is trichloroethylene banned in US?
To date, neither ban – intended to protect public health – is in place. Instead, the Trump Administration has taken every opportunity to delay these bans – disregarding the intent of the nation’s reformed chemical safety law and putting the health of workers and the public at risk.
