Question

What is the product obtained when acetylene is treated with $\mathrm{HBr}$?

Answer 1

Formation of product:

• Ethylidene bromide is formed when acetylene is reacted with hydrogen bromide.

Chemical reaction

$\underset{\mathrm{Acetylene}}{\mathrm{CH}\equiv \mathrm{CH}}+\mathrm{HBr}\to \underset{\mathrm{Vinyl}\mathrm{bromide}}{{\mathrm{CH}}_2=\mathrm{CHBr}}\stackrel{\mathrm{HBr}}{\to }\underset{\mathrm{Ethylidene}\mathrm{bromide}}{{\mathrm{CH}}_3{\mathrm{CHBr}}_2}$
