Question

укажите направление смещения электронов в следующих веществах LiF, F2, OF2, P2O3, CaC2 ПОМОГИТЕ ПОЖАЛУЙСТА

Answer 1

В первом к F (т.к. фтор-самый электроотрицательный элемент), в третьем тоже к F, в четвертом к O3, а в последнем к C. 

Answer 2

Direction of Electron Displacement in Various Substances

In the following substances, the direction of electron displacement can be determined based on their chemical properties:

1. LiF (Lithium Fluoride): - In lithium fluoride, the electron displacement occurs in such a way that the lithium atom loses an electron to the fluorine atom, resulting in the formation of Li+ and F- ions. - This indicates that the electron displacement is from lithium to fluorine. - Source: Chemistry LibreTexts [[1]]

2. F2 (Fluorine Gas): - In the case of fluorine gas, the electron displacement occurs within the molecule due to the high electronegativity of fluorine. - Each fluorine atom in the F2 molecule shares one electron with the other fluorine atom, forming a single covalent bond. - Source: Chemistry LibreTexts [[2]]

3. OF2 (Oxygen Difluoride): - In oxygen difluoride, the electron displacement occurs in such a way that the oxygen atom gains a partial negative charge, while the fluorine atoms gain partial positive charges. - This indicates that the electron displacement is from fluorine to oxygen. - Source: Chemistry LibreTexts [[3]]

4. P2O3 (Phosphorus Trioxide): - In phosphorus trioxide, the electron displacement occurs in such a way that the oxygen atoms gain partial negative charges, while the phosphorus atom gains a partial positive charge. - This indicates that the electron displacement is from phosphorus to oxygen. - Source: Chemistry LibreTexts [[4]]

5. CaC2 (Calcium Carbide): - In the case of calcium carbide, the electron displacement occurs in such a way that the calcium atom loses two electrons to the carbon atoms, resulting in the formation of Ca2+ and C2- ions. - This indicates that the electron displacement is from calcium to carbon. - Source: Chemistry LibreTexts [[5]]
