The distinct experimentally observed regiochemistries of the reactions between mesoionic munchnones and beta-nitrostyrenes or phenylacetylene are shown by DFT/BDA/ETS-NOCV analyses of the transition states to be dominated by steric and reactant reorganization factors, rather than the orbital overlap con...
This is why iron was commonly used. Lighter materials were weighted down and balanced with ballasts and weights. The reason it needed to be so heavy was because of the resistance you feel when you push the cup into the water. The force of the water pushes the air up, compressing it as...
