How does the attraction between molecules affect the ability of a liquid to flow?
The attraction between molecules, known as intermolecular forces, affects the ability of a liquid to flow by influencing the viscosity of the liquid. Stronger intermolecular forces result in higher viscosity and reduced flowability, as molecules require more energy to overcome these forces and move past each other. On the other hand, weaker intermolecular forces lead to lower viscosity and better flowability as molecules can move more easily.
What would biocheemists call the result of chaning many of these molecules together?
Biochemists would call the result of chaining many molecules together a polymer. Polymers are large molecules made up of repeating units called monomers. The process of linking monomers together is known as polymerization.
What is the formula of iodine crystals?
Iodine exists as I2. The crystal of iodine is formed simply by the interaction of iodine molecules as a result of Van de Waals forces, which allows for these molecules to bond together to form a solid.
What are factors affecting London forces?
The factors affecting London forces are the size of the atoms or molecules involved (larger sizes result in stronger forces), the shape of the atoms or molecules (more surface area allows for stronger forces), and the polarizability of the atoms or molecules (more easily distorted electron clouds lead to stronger forces).
What affect the strength of attraction between molecules?
The strength of attraction between molecules is influenced by factors including the types of intermolecular forces present (such as hydrogen bonding, dipole-dipole interactions, or van der Waals forces), the molecular shape and size, and the polarity of the molecules. Stronger intermolecular forces result in higher attraction between molecules.
What are the intermolecular forces of I2?
Iodine is bound together by van der Waals forces.
What type of bonding is found in wax?
Wax is typically composed of nonpolar molecules such as hydrocarbons, which are held together by weak van der Waals forces. These forces result from temporary dipoles formed by the movement of electrons in the molecules.
Intermolecular forces of F2?
Fluorine (F2) molecules are held together by weak van der Waals forces, specifically London dispersion forces. These forces result from temporary dipoles induced in the molecules due to electron movement. Due to the small size of the fluorine molecule, the van der Waals forces between F2 molecules are relatively weak.
What is the result of intermolecular forces being repulsive and attractive varying distances?
Once molecules become close enough to touch, intermolecular forces become repulsive. This is what prevents one molecule from overlapping another. Intermolecular forces pull molecules together at a long range and hold them apart at short range.
What do dipole-dipole forces do?
Hold Polar molecules together
High vapor preassure weak intermlecular force?
High vapor pressure is a result of weak intermolecular forces between molecules. When the forces holding molecules together are weak, it is easier for molecules to escape into the vapor phase, leading to higher vapor pressure. This is commonly observed in substances with low boiling points.
What is responsible for the unbalanced forces in water?
Unbalanced forces in water are typically caused by variations in pressure, such as differences in temperature, density, or flow rate. These variations create differences in forces that result in the water moving in a specific direction.
what attractive force holds molecules of the same substance together?
Cohesion
What is the nature of attractive force among molecules in liquid bromine?
The attractive force among molecules in liquid bromine is primarily due to London dispersion forces, which are weak intermolecular forces that result from temporary fluctuations in electron distribution within molecules. These forces are responsible for holding the molecules together in the liquid phase.
Why bare covalent molecules typically liquids or gases?
Bare covalent molecules are typically liquids or gases because they have weak intermolecular forces between the molecules. These weak forces are not strong enough to hold the molecules closely together in a solid form, leading to a lower melting point and boiling point. As a result, bare covalent molecules tend to exist as liquids or gases at room temperature.
The dominant force holding the units together in solid iodine?
In solid iodine, the dominant force holding the units together is the weak van der Waals forces. These forces are the result of temporary dipoles formed by the movement of electrons, leading to a slight attraction between the iodine molecules.
What effect does branching of an alkane chain has on its boiling point?
Branching of an alkane chain decreases the boiling point. This is because branching disrupts the ability of molecules to stack closely together, reducing the overall intermolecular forces (London dispersion forces) between molecules. As a result, less energy is required to overcome these weaker forces, leading to a lower boiling point.
