Explain why ethanol is not soluble in cyclohexane. Also, how do you figure out whether something is polar or nonpolar?
ethanol is polar while cyclohexane is nonpolar.

Why is ethanol insoluble in cyclohexane
The concentrated sulfuric acid we use in the laboratory is 98.0 percent H2SO2 by mass. Calculate the molality of the acid solution.the density of the solution is 1.83g/ML
Ethanol is not soluble in cyclohexane due to differences in their molecular structures and intermolecular forces.
Ethanol (C2H5OH) is a polar molecule because it contains polar bonds (C-O and O-H) and has a slight separation of charge across the molecule. The oxygen atom (O) in ethanol is more electronegative than the carbon (C) and hydrogen (H) atoms, creating a partial negative charge on the oxygen and partial positive charges on the carbon and hydrogen atoms. This imbalance of electron distribution results in a polar molecule.
On the other hand, cyclohexane (C6H12) is a nonpolar molecule. All carbon-carbon (C-C) and carbon-hydrogen (C-H) bonds are nonpolar because carbon and hydrogen have similar electronegativities. Additionally, the symmetrical shape of cyclohexane prevents any separation of charge across the molecule.
When it comes to determining whether a molecule is polar or nonpolar, there are a few factors to consider:
1. Molecular geometry: The shape of the molecule can reveal its polarity. If the molecule has polar bonds, the molecular geometry may determine if the overall molecule is polar or nonpolar. For example, a molecule with polar bonds can be nonpolar overall if the polar bonds are arranged symmetrically around the central atom, canceling out the polarity.
2. Electronegativity: The difference in electronegativity between atoms within a molecule can indicate its polarity. When there is a significant difference in electronegativity, the molecule is likely polar, while a small or no difference suggests nonpolarity.
3. Molecular symmetry: Symmetry plays a significant role in determining whether a molecule is polar or nonpolar. A molecule with symmetrical geometry, where polar bonds are equally distributed on all sides, tends to be nonpolar. However, if the molecule has an asymmetrical distribution of bonds or lone pairs, it is likely to be polar.
4. Dipole moments: The presence of a dipole moment in a molecule indicates polarity. A dipole moment occurs when there is an unequal distribution of charge, resulting in a separation of positive and negative poles within the molecule. If a molecule has a net dipole moment, it is polar.
To determine whether something is polar or nonpolar, you can use various tools and resources. One method is to analyze the molecular structure and bond types by using structural formulas or models. Additionally, electronegativity values of atoms can be checked on the periodic table. Online applications and software packages for molecular modeling and simulation can also help visualize and analyze molecular polarity.
