Option A, I2, has only London forces.
London forces, also known as dispersion forces, are the weakest type of intermolecular forces. They are present in all molecules, but they are especially important in nonpolar molecules like I2. London forces are caused by fluctuations in the distribution of electrons in a molecule, which result in temporary dipoles. These dipoles can interact with neighboring molecules, creating attractive forces.
In contrast, NH2, OCl2, and SH2 all contain polar covalent bonds, which give rise to additional intermolecular forces, such as dipole-dipole interactions and hydrogen bonding. Dipole-dipole interactions are stronger than London forces, and hydrogen bonding is the strongest type of intermolecular force.
So, while London forces are present in all molecules, they are the only type of intermolecular force present in I2. The other options, NH2, OCl2, and SH2, also have London forces, but they have additional intermolecular forces due to the presence of polar covalent bonds and hydrogen bonding.

which of the following is expected to have the greatest viscosity? question 2 options: a) c5h12 b) c5h11oh c) ch4 d) c6h14
The expected to have the greatest viscosity is option c.C5H11OH.
The resistance of a fluid (liquid or gas) to a change in shape or motion of adjacent sections relative to one another is known as viscosity. Viscosity is a sign of flow resistance.
The thickness of a fluid is another name for viscosity. The state of a fluid, including its temperature, pressure, and rate of deformation, affects its viscosity. In some circumstances, the dependence on some of these traits is minimal. For instance, the rate of deformation has no effect on the viscosity of a Newtonian fluid. Super fluids are the only fluids that exhibit zero viscosity, or no resistance to shear stress; in all other fluids, positive viscosity is required by the second law of thermodynamics. Ideal or inviscid fluids are those with no viscosity.

a student proposes the following lewis structure for the hydrogen cyanide molecule. assign a formal charge to each atom in the student's lewis structure.
To assign formal charges to the atoms in a Lewis structure, you need to count the number of electrons around each atom and compare it to the number of electrons it would have in an isolated (neutral) atom of the same element.
In the hydrogen cyanide (HCN) molecule, nitrogen (N) is the central atom and has five electrons in its valence shell. Hydrogen (H) atoms each have one electron in their valence shell. To form a stable Lewis structure, N must have an octet of electrons (eight electrons in its valence shell), so it must share electrons with the hydrogen atoms.
Here's the calculation for each atom:
Nitrogen: In an isolated N atom, there would be 5 electrons in its valence shell. In the HCN molecule, N has 5 shared electrons and 8 electrons in total, giving it a formal charge of 0.
Hydrogen: In an isolated H atom, there would be 1 electron in its valence shell. In the HCN molecule, each H has 1 shared electron, giving it a formal charge of 0.
So, the Lewis structure of HCN has formal charges of 0 on all atoms, which means it is a neutral species

what can you conclude about the solvents used and their reaction with the markers?
The type of solvent used with a marker can greatly affect the reaction and outcome of the marker. When selecting a solvent, it is important to consider the polar or non-polar nature of both the solvent and the marker in order to achieve the desired result.
Solvents are liquids that are used to dissolve substances and are an important aspect of chemical reactions and processes. When it comes to markers, the type of solvent used can greatly affect the reaction and outcome of the marker.
In general, solvents can be classified as polar or non-polar. Polar solvents, such as water, have a positive and negative end, while non-polar solvents, such as oil, have a more uniform distribution of electrons. The solubility of a substance is determined by its polar or non-polar nature and the polar or non-polar nature of the solvent.
Markers contain various types of dyes or pigments that can be either polar or non-polar. When a polar solvent, such as water, is used with a polar marker, the marker will dissolve easily, leading to a more intense and uniform color. On the other hand, when a non-polar solvent, such as alcohol, is used with a polar marker, the marker may not dissolve as well and the color may be lighter or less intense.

does diphenyl ether exhibit a molecular dipole moment
The presence of a large molecular dipole moment in diphenyl ethers leads unequivocally to a centrosymmetric crystal structure
A dipole moment is produced when electrons are distributed unevenly among atoms in a molecule. This happens when one atom possesses a lone pair of electrons and the difference in electronegativity vector points in the same direction, or when one atom is more electronegative than another, causing that atom to pull more strongly on the shared pair of electrons. The water molecule, which consists of one oxygen and two hydrogen atoms, is one of the most prevalent instances. Each hydrogen has a partial positive charge, while oxygen has a partial negative charge due to variances in electronegativity and lone electrons.

Why is dissolving salt in water an endothermic process?
The reason dissolving salt in water an endothermic process is because it requires the absorption of heat from the environment. This happens because the bonds between the salt ions and the water molecules are disrupted, and energy is needed to overcome these bonds and allow the salt ions to dissolve in the water.
Any thermodynamic process with an increase in the enthalpy H (or internal energy U) of the system is referred to as an endothermic reaction in thermochemistry (from the Greek v (endon) "inside" and -(therm) "hot, warm"). A closed system often transfers heat into itself during such a process by absorbing thermal energy from its surroundings.
As a result, an endothermic reaction typically results in a rise in the system's temperature and a fall in the environment's. It could involve a chemical reaction, such when ammonium nitrate (NH4NO3) is dissolved in water (H2O), or a physical action, like when ice cubes melt.

atoms involved in a blankbond equally share electrons; there is no charge separation to the molecule.
Atoms involved in a non-polar equally share electrons; there is no charge separation to the molecule.
A nonpolar bond is a type of covalent bond in which the electrons are shared equally between the two atoms forming the bond. This means that the electronegativity of both atoms is similar and there is no separation of charge within the molecule.
As a result, nonpolar bonds are characterized by an absence of polarity or a lack of separation of electric charge.
Examples of nonpolar bonds include bonds between two identical atoms, such as H-H or C-C, as well as bonds between atoms with similar electronegativities, such as N-H or C-O. These bonds are found in molecules that are considered to be nonpolar, such as methane (CH4) and carbon dioxide (CO2).
