Give two reactions of electrophilic addition on acetylene along with their mechanism.
Starting from acetylene how will you obtain:
(i) Ethylidene iodide
(ii) Dichloro acetaldehyde
(iii) Ethylene?
(i) The addition of water in the presence of dilute H2SO4 and HgSO4.
(ii) The addition of HCN in the presence of Ba(CN)2.
(iii) The addition of acetic acid in the presence of Hg2+ ion.
Starting from Ethyne, how will you prepare (No mechanism):
(i) Ethanol (ii) Vinyl chloride (iii) Methyl vinyl ether (iv) Vinyl acetate?
