Question

How is ethyl bromide prepared from 1) ethyl alcohol 2) ethane 3) ethene​

Answer 1

ethyl alcohol + PBr3 = ethyl bromide
ethane+ Br2 h(nu) = ethyl bromide
ethene + HBr = ethyl bromide

Answer 2

Answer: Ethyl bromide can be prepared by the following ways:-

a. Ethyl alcohol to Ethyl bromide.

Ch₃-Ch₂-OH + (NaBr + H₂SO₄) ⇒ Ch₃-Ch₂-Br

b. Ethane to Ethyl bromide.

Ch₃-Ch₃ + Br₂ (In the presence of U.V. rays) ⇒ Ch₃-Ch₂-Br

c. Ethene to Ethyl Bromide

Ch₂=Ch₂ + H-Br ⇒ Ch₃-Ch₂-Br
