How will you convert a ethane to bromoethane?

Ethane is converted to bromoethene by first reacting ethane with bromine in presence of U.V light to form bromoethane. Then bromoethane is reacted with alcoholic potassium hydroxide to form ethene.

How is bromoethane prepared from I ethane II ethanol?

Answer: It is usually prepared by the addition of HBr to ethene: H2C=CH2 + HBr → H3C-CH2Br. Bromoethane is inexpensive and would rarely be prepared in the laboratory. A laboratory synthesis includes reacting ethanol with a mixture of hydrobromic and sulfuric acids.

How do you convert bromoethane to ethene give equation?

C2H5Br+KOH[alcohol]→C2H4+KBr+H2O.

How do you convert ethanol to bromoethane?

Add PBr3 to ethanol. That will give bromoethane. Also HBr can be used to prepare bromoethane. HBr reacts with ethanol to give bromoethane.

What happens when ethene reacts with HBr?

(B) HBr on ethylene – Alkenes react with hydrogen bromide in the cold. The double bond breaks and a hydrogen atom ends up attached to one of the carbons and a bromine atom to the other. In the case of ethene, bromoethane is formed.

How is bromoethane obtained from alkene?

Alkenes react with hydrogen bromide in the cold. The double bond breaks and a hydrogen atom ends up attached to one of the carbons and a bromine atom to the other. In the case of ethene, bromoethane is formed.

How are the following compounds prepared from ethane chloroethane bromoethane?

(1) Chlorination of ethane : When ethane (excess) is reacted with a limited quantity of chlorine in the presence of diffused sunlight or U.V. light or at high temperature, chloroethane is obtained. (2) Bromination of ethane : When ethane is heated with Br2 in the presence of anhydrous AlBr3, bromoethane is obtained.

How will you prepare ethene from bromoethane by using ALC Koh?

When bromoethane is heated with alcoholic potassium hydroxide, a water molecule is eliminated from the bromoethane molecule and ethene is given as the product.

What are the properties of ethane?

Ethane appears as a colorless odorless gas. It is easily ignited. The vapors are heavier than air.

  • Ethane, refrigerated liquid appears as a colorless odorless very cold liquid. Boils at -88.6°C.
  • Ethane is an alkane comprising of two carbon atoms. It has a role as a refrigerant and a plant metabolite.

    • What is the use of bromoethane?

    Bromoethane is a bromoalkane that is ethane carrying a bromo substituent. It is an alkylating agent used as a chemical intermediate in various organic syntheses. It has a role as a carcinogenic agent, a solvent, a refrigerant, a local anaesthetic and an alkylating agent.
