by removal of hydrogen molecule one more pi bond will be formed between carbons thus ethene will convert in ethyne
Edit by some other dude named Timaeus:
Yeah...no. That's not right at all. This is how it's done:
First, halogenation of ethene to form a vicinal dihalide. Then a second order elimination reaction, let's say using a bulky nucleophile like tert-butoxide, to convert it to a bromoethene. Then just once more with the E2 reaction to form ethyne.
Ethylene is derived from crude oil. The process of fractional distillation is used to separate crude oil into its main components (ie. its relevant carbon chain length). The cracking of the large hydrocarbons, thermally or catalytically, breaks them into smaller hydrocarbons. Ethylene is produced in this way.
Take ethene. Add Br2 to get the dibromo derivative. Then do a double dehydrohalogenation with Alcoholic KOH to get ethyne.
CH2=CH2 + Br2 ---> CH2Br-CH2Br + 2KOH(Alcoholic)---> CH-=CH + 2KBr + 2H2O
Ethylene is produced by heating hydrocarbons to intense heats. The resulting mixture is then repeatedly compressed and distilled to remove the ethylene from it.
Hydrogenation in presence of Ni as catalyst.
Mono halogenation followed by reaction with alcoholic KOH.
as it can prepared from c2
dunnno
according to me, ethane can't be prepared from ethanol. but you can prepare ethene from ethanol by treating ethanol with conc. H2SO4 (95%) In 440 K Temperature with release of water molecule.
in first step prepare ethane to chloro ethane fallowed by wurtz reaction. chloro ethane can be prepared free radical reaction btw ethane and chlorine
ethanol
There are many methods. A few are listed below: 1. by the hydrogenation of ethene. 2. by the hydrogenation of ethyne. 3. by the reaction of methyl halide in presence of sodium (Wurtz reaction).

Ethane is prepared in the laboratory by the heating of ethanol

Ethane is an alkane with the chemical formula C2H6. Ethanol is an alcohol with the chemical formula C2H5OH, corresponding to ethane.

1,2 dibromoethane and 1-bromo, 2-chloro ethane and 2-bromo ethanol

Combustion of Ethane: 2C2H6+7O2-->4CO2+6H2O Combustion of Ethanol: C2H5OH+3O2-->2CO2+3H2O

The product formed when ethane reacts with hydrochloric acid is ethanol. The reaction is referred to as a redox reaction because oxidation and reduction takes place at the same time.
If there is a sufficient amount of oxygen, the products are carbon dioxide and water. With proper catalysis and control of reaction conditions, ethanol, ethanal, and/or ethanoic acid could also be formed.
