Question3.7 LnC2 are good conductors of electricity and form ethyne, C2H2, on hydrolysis (as does CaC2, traditionally used in ‘acetylene’ headlamps on early cars and bicycles). Explain these observations. Answer 3.7 These compounds have the structure M3+ (C2− 2 )(e−).The delocalized electrons cause the high conductivity. The ethynide ions react with water thus: C2− 2 (s)+2H 2O(1)→C2H2(g)+2 OH −(aq)
