Conclusions
-
1.
The predominant direction of the reaction of acetylene with a molecule of lithium hydroxide in both the dissociated and undissociated states is the formation of the molecular π complex C2H2· LiOH.
-
2.
The formation of the complex C2H2· LiOH is accompanied by significant lowering of the energy levels of the vacant π orbitals of acetylene, which creates favorable conditions for nucleophilic attack on the triple bond.
