In the modern quantum-based atomic theory, what is the name given to a particular space around the nucleus in which an electron moves? a. orbit b. nucleus c. energy level d. orbital

-

Orbital

Explanation:-

According to modern quantum-based atomic theory, Orbital is the place where the probability of finding an electron is maximum.

So it is the particular space around the nucleus in which an electron moves.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
