How do you convert 1 2 dibromoethane to Ethyne give reason?
When 1-Bromoethane is treated with another compound called sodamide with chemical formula ( ) due to occurrence of de-hydrogenation and de-halogenation, it leads to the formation of ethyne. 4. Thus the product ethyne is obtained from 1,2-dibromoethane through a process such as de-hydrogenation and de-halogenation.
What is the best way to prepare 1/2 dibromoethane is to treat?
1, 2 – dibromoethane gives by treating with Zn dust under suitable conditions.
Which of the following with aqueous KOH will give acetaldehyde?
A dihalogen derivative ′X′ of a hydrocarbon with three carbon atoms reacts with alcoholic KOH and produces another hydrocarbon which forms a red precipitate with ammoniacal Cu2Cl2. ′X′ gives an aldehyde on reaction with aqueous KOH.
What product is obtained when 1/2 dibromoethane is treated with alcoholic KOH Mcq?
C2H5Br +KOH = C2H4 + KBr + H2O which is a laboratory preparation of ethene.
Where does 1 2 dibromoethane come from?
It also occurs naturally in small amounts in the ocean where it is formed, probably by algae and kelp. It is a colorless liquid with a mild, sweet odor. Other names for 1,2-dibromoethane are ethylene dibromide, EDB, and glycol bromide.
What is the LD50 value of 1 2 dibromoethane?
The known empirical LD50 values for 1,2-dibromoethane are 140 mg kg –1 (oral, rat), and 300.0 mg kg –1 (dermal, rabbit). 1,2-Dibromoethane is a known carcinogen, with pre-1977 exposure levels ranking it as the most carcinogenic substance on the HERP Index.
What is the CAS number for dibromoethane?
