Answer:
7. ..............................
Answer:
The difference in electronegativity between fluorine (4.0) and hydrogen (2.1) is quite high, so the shared electrons spend much more time in the vicinity of the fluorine atom. As a result, fluorine carries a partial negative charge in this molecule, whereas hydrogen carries a partial positive charge
Explanation:
1 mole contains 6.023 *10^23 molecules
Answer:
The C22- ion is stable
Explanation:
The C22- ion is a stable ion having a bond order of three. It has a favourable stabilization energy of 6∆ compared to 4∆ in C2. In the carbide ion carbon firms three bonds rather than two in dicarbon, hence the formation of the carbide ion is preferred. The molecular orbital configuration of the carbide ion is shown in the image attached.
