So, dipole-dipole forces are forces of attraction between polar molecules. These molecules attract when the positive end of one of them is close to the negative of the other. Given the above, F₂ and Cl₂ are non-polar molecules and ClF and NF₃ are polar molecules. Then ClF and NF₃ have polar interactions (dipole-dipole forces).Which of the following substances have polar interactions (dipole-dipole forces) between molecules? If you can't find your institution, please check your spelling and do not use abbreviations. If your institution is not listed, please visit our Digital Product Support Community .A network of partial + and - charges attract molecules to each other. Dipole-dipole interactions are stronger intermolecular forces than Dispersion forces. They occur between molecules that have permanent net dipoles (polar molecules). For example, dipole-dipole interactions occur between SCl 2 molecules, PCl 3 molecules and CH 3 Cl molecules.So, dipole-dipole forces are forces of attraction between polar molecules. These molecules attract when the positive end of one of them is close to the negative of the other. Given the above, F₂ and Cl₂ are non-polar molecules and ClF and NF₃ are polar molecules. Then ClF and NF₃ have polar interactions (dipole-dipole forces).Polar molecules align so that the positive end of one molecule interacts with the negative end of another molecule. Unlike covalent bonds between atoms within a molecule (intramolecular bonding), dipole-dipole interactions create attractions between molecules of a substance (intermolecular attractions).

An example of a dipole-dipole interaction can be seen in hydrogen chloride (HCl): the positive end of a polar molecule will attract the negative end of the other molecule and influence its position. Polar molecules have a net attraction between them. Examples of polar molecules include hydrogen chloride (HCl) and chloroform (CHCl 3).The three main intermolecular forces are London dispersion forces, dipole-dipole interactions and hydrogen bonding. Dipole-dipole interactions are caused by the attraction of two polar molecules. If a molecule has an area of positive charge and an area of negative charge it is said to be polar or have a dipole moment.Intermolecular Forces: Intermolecular forces are those forces that occur between different molecules. These forces include dipole-dipole interactions, ionic interactions, and dispersion forces.The contradictions get up because you're comparing apples with oranges. for instance the C-F bond is more advantageous than the C-Cl bond; the C-F bond is likewise extra polar. yet in reactions the C-F bond may be damaged extra actual - because then you should think concerning the hot bonds F varieties, and seeing that F is so reactive they could also be very solid, hence the reaction

Which of the following pairs will form polar covalent bond

The answer is choice c.. The intermolecular force of attraction between polar molecules is called dipole-dipole interaction. Thus, we have to identify which among the molecules is polar.Which of the following substances have polar interactions (dipole-dipole forces) between molecules?... Questions in other subjects: Engineering, 20.04.2020 22:35Which of the following substances have polar interactions (dipole-dipole forces) between molecules?-ClF-NF3. Which substances exhibit only London (dispersion) forces?-Cl2-He. Which molecules can hydrogen bond?-HF-CH3OH. Classify each substance based on the intermolecular forces present in that substance.A dipole-dipole interaction is an attraction or repulsion between polar molecules. The positive region of one molecule is attracted to the negative region of another and repulsed by the positive region of another molecule. A Hydrogen bond is a dipole-dipole interaction.Therefore, the tendency for polar molecules to interact with non-polar molecules is minimum. Because the energy released by the formation of dispersion forces between polar and non-polar molecules are not enough to break strong dipole-dipole interactions between polar molecules. Therefore non-polar solutes cannot be dissolved in polar solvents.
