Intermolecular forces

shape and functional groups. These factors significantly influence the strength of the intermolecular forces of attraction present; and the nature and strength of intermolecular forces determine the variations in boilingpoints of organic compounds. The boiling point of a liquid is the temperature at which its vapor pressure equals the external or atmospheric pressure. At this temperature, every molecules of the liquid acquire enough kinetic energy to overcome the intermolecular forces attracting them to the other molecules. Therefore, boiling points…

Intermolecular Forces Intermolecular forces are the result of attractive or repulsive forces between atoms, molecules or ions, primarily as a result of electrostatic attractions; these forces act between discrete molecules. Intermolecular forces are weak forces but without them life as we know it would not be possible: water vapor would not condense into its liquid (or solid forms) if its molecules did not attract each other, and all matter, in fact, would exist as gases. The physical states…

effective these bonds are. The structure of the molecule itself is held together by the intramolecular forces, which are the internal forces of a molecule, such as the attraction and repulsion of electrons to the protons in the nucleus. The external forces on a molecule, which are called the intermolecular forces, such as electronegativity, help to determine the boiling and melting points of each element. Each of these intermolecular forces differs in strength, but even the strongest one is…

In this lab, the guiding question is “How does the surface tension and relative intermolecular forces compare between certain substances?” In order to fully understand this guiding question, we have to know what is the surface tension and intermolecular force. The definition of surface tension is “the inward force, or pull, that tends to minimize the surface area of a liquid, and the definition of intermolecular force is the force, or pull, between the molecular which has polar…

EXPERIMENT 1 INTERMOLECULAR FORCES OF ATTRACTION Group 5 Cabale, Sheena Marie N. Hernaez, Neil Chester C. Rivera, Ian Howell D. Ronquillo, Aljon A. Venus, Mark Joven C. I. Introduction The attraction forces between molecules are called intermolecular forces. It is the non-ideal behavior of gases. On the other hand, the attraction forces within the molecule are called intramolecular forces. (Chang, 2014) There are different types of intermolecular forces. These are dipole-dipole, dipole-induced…

Purpose: The main purpose behind this experiment is to know the how the strength of the intermolecular forces changes with the molecular size and structures. Based on the examination of the evaporation of different liquids and by determining the vapor pressure of different alcohols at a different temperature. Producer: There will be two parts in this experiment to know the strength of the intermolecular forces of different liquids, to conclude the role of the molecular size and structure of…

INTRODUCTION The determination of whether a body of water is fit for consumption and all other factors concerning its physical and chemical state is known as water quality. Water (H2O) has a covalent bond as it consists of two non-metal substances (intramolecular bond). Intramolecular forces are the forces inside an individual molecule (chemical bonds) while intermolecular forces occur between molecules (physical interactions). Hydrogen can act as a metal or a non-metal and oxygens bond with…

By the cause of branching the chain makes the molecule more compact, weakens the crystal lattice structure of the compound and thus drops the surface area. Hence, spreading forces reduces as there are fewer places for interaction, so decreasing the amount of energy required to break the intermolecular forces of attraction. 2-hexanone has the lowest point boiling point, as it much more branched and the third carbon has a functional group (double bond O), leading a high compacted molecule.…

supported by the basic knowledge of intermolecular forces regarding hydrogen bonds, London Dispersion forces, as well as Dipole-Dipole, and simple ionic bonds in the case of sodium chloride. The molecule with the least amount of these forces is the one with the weakest bonds,…

boiling point increase when the addition of an extra carbon atom in a straight-chain homologous series of saturated alcohols occurs?” On average, as per calculations conducted, the boiling point increases by a magnitude of approximately 14.1 ℃. Granted such quantitative evidence, in addition to its corresponding visual plotting detailed in figure 2.1, it could reasonably be determined that a quite linear correlation indeed exists between carbon-chain length and boiling point. This is highly…
