Question
Give two reactions of electrophilic addition on acetylene along with their mechanism.
Solution
(i) The addition of halogen: Chlorine and bromine add on to acetylene to form addition product.
Mechanism. It involves electrophilic addition and consists of the following steps:
Step II. The electrophilic addition is repeated again when the final compound gets formed.
(ii) The addition of hydrogen halides. The hydrogen halides (HCl, HBr or HI) add-on triple bond to give rise to haloalkene or haloalkane.
Mechanism. It involves electrophilic addition and consists of the following steps:
