Shoo ! Don't sPam -_-
how is ethane prepared from bromoethane ? ​

Answer 1

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.

Answer 2

Ethane prepared from Bromoethane

First, we will convert Bromoethane to ethene

CH3–CH2–Br + alc.KOH ——> CH2=CH2 + KBr + H2O

Ethene is then reduced to ethane with Ni/H2

CH2=CH2 + H2 ——> CH3–CH3
