With the advancement of science, electrons seemed to possess both particle and wave nature.
this is called the dual nature where electrons have both particle and wave properties.
earlier it was believed that electrons used to orbit around the nucleus in orbits.
Later it was found that electrons do not have fixed positions, the exact momentum and position of electrons cannot be determined at the same time
therefore the wave mechanical model was introduced which introduced orbitals.
Orbitals are spaces in which electrons are most likely to be found. These regions have the highest probability of an electron being found here.
correct answer is 3) an electron

Answer:
<span>Dipole-Dipole Forces are common </span><span>to all polar molecules but not non polar molecules.
Explanation:
An Asymmetrical molecule having a region of high electron density (partial negative) and lower density (partial positive) interacts with its neighbor molecules through Dipole-Dipole Interactions. The partial positive part of one molecule interacts with the partial negative part of another.
Example:
Acetone having a partial positive carbon (of carbonyl group) and partial negative oxygen interacts through Dipole-Dipole forces. Hence, acetone does not involves Hydrogen Bond interactions.</span>

The compound with a chemical formula of C₃H₈ is propane. The subscripts actually represent the number of the individual atoms in 1 particle of the compound. Since there are the same number of atoms per mole of any substance, the subscript can also represent the moles. Through stoichiometric calculations, the solution is as follows:
Moles of Carbon = 11.2 moles H * 3 mol C/8 mol H = <em>4.2 moles</em>
