Conclusions
-
1.
In the transition from inert solvents to solvating solvents, the internal chemical shift of the ethyl protons for ethyl protons for ethyl derivatives of silicon, germanium, tin, and mercury increases.
-
2.
The donor activity of the solvents depends substantially on the nature of the acceptor.
-
3.
The variation of the electronegativity of the elements of subgroup IV B: C (2.60)>Pb (2.10)>Ge (1.90)>Sn (1.84)>Si (1.82) does not agree with the arrangement of these elements in the Mendeleev periodic system.
-
4.
The variation of the spin-spin interaction constant JCH 2—199Hg for diethylmercury in various solvents depends chiefly on the change in the s-electron density on the protons.
