What type(s) of intermolecular forces are expected between seh2 molecules?
2 answers:
Answer:
Induced and dipole forces.
Explanation:
Hello,
Due to its structure, , one identifies the following two intermolecular forces:
- Induced: Ion-Induced Dipole Forces
At first, an ion-induced dipole attraction is present as a weak force which results when the approach of an ion induces a dipole in this nonpolar molecule by disturbing the arrangement of electrons.
- Dipole forces.
Now, dipole-dipole forces are present in such molecule as attractive forces between the positive end of one of the polar molecule and the negative end of another polar space in the molecule.
Best regards.

Answer:
Explanation:
To answer this question successfully, we need to remember that atoms are neutral species, since the number of protons, the positively charged particles, is equal to the number of electrons, the negatively charged particles. That said, we may firstly find an atom which has 3 electrons (and, as a result, 3 protons, as it should be neutral).
The number of protons is equal to the atomic number of an element. We firstly may have an atom with 3 protons and 3 electrons (atomic number of 3, this is Li).
Similarly, we may take the atomic number of 4, beryllium, and remove 1 electron from it. Upon removing an electron, it would become beryllium cation, .
We may use the same logic going forward and taking the atomic number of 5. This is boron. In this case, we need to remove 2 electrons to have a total of 3 electrons. Removal of 2 electrons would yield a +2-charged cation: .
