Why does like dissolves like intermolecular forces?
Main Idea: “Like dissolves like.” The stronger the intermolecular forces between solute molecule and solvent molecule, the greater the solubility of the solute in the solvent. Between two polar molecules, the molecule with the smaller hydrocarbon portion (or the larger polar portion) is more soluble in water.
Why does like dissolve like polarity?
In this way, polar molecules aggressively seek each other out, excluding non-polar molecules from mixing with them and forming a solution. While non-polar molecules form much weaker attractions for each other, they will mix and form solutions. Like dissolves like!
What is meant by likes dissolve likes?
• Chemist’s rule of thumb – like dissolves like. • A chemical will dissolve in a solvent if it has a similar structure to the solvent. • Polar molecules and ionic compounds will be more soluble in polar solvents.
Does dipole-dipole dissolve water?
Water is often called the universal solvent. It dissolves polar compounds through dipole-dipole interactions.
What is ion dipole forces?
An ion-dipole force is an attractive force that results from the electrostatic attraction between an ion and a neutral molecule that has a dipole. Most commonly found in solutions. A negative ion (anion) attracts the partially positive end of a neutral polar molecule.
What intermolecular forces are present in kmno4?
Potassium permanganate is very soluble in water.
- KMnO4 is an ionic substance.
- Water contains hydrogen bonds,
- ION – DIPOLE FORCES EXSIST between these two substances.
- These are relatively strong intermolecular forces and that accounts for the solubility of ionic substances in polar solvents.
What does like dissolves like mean quizlet?
“Like dissolves like” means polar solutes are more soluble in polar solvents and nonpolar solutes are more soluble in nonpolar solvents.
What does like dissolves like mean Quizizz?
Q. What does “like dissolves like” mean? polar solvents dissolve in polar solutes.
Is acetone London dispersion forces?
Acetone molecules are attracted by both dipole-dipole interactions and London forces.
Do I2 and C6H14 have similar intermolecular interactions?
I2 and C6H14 have similar intermolecular interactions, and I2 and H2O do not.
What is dipole induced dipole?
Dipole-Induced Dipole Forces A dipole-induced dipole attraction is a weak attraction that results when a polar molecule induces a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons in the nonpolar species.
Are dipole dipole forces soluble in hexane?
‘like dissolves like” substances that are mostly polar (like glucose) dissolve in polar solvents like water but not in a nonpolar solvent like hexane, presumably since the dipole forces (specifically H-bonds) holding polar solute molecules together can be replaced with polar solute-solvent interactions (H-bonds).
What is the meaning of like dissolves like?
“Like dissolves like” is an expression used by chemists to state that polar solvents dissolve polar solutes; non-polar solvents dissolve non-polar solutes.For example: water is polar, oil is non-polar. Water will not dissolve oil. Water is polar, and table salt (NaCl) is ionic, which is extremely polar.
What is an example of a nonpolar compound that dissolves in water?
Oxygen gas, an nonpolar molecules, does dissolve in water and it is this oxygen that the fish take in through their gills. Or, one more example of a nonpolar compound that dissolves in water is the reason we can enjoy carbonated sodas.
What is the process of dissolution?
The process of dissolution occurs when a solute (solid, liquid, or gas) is placed in a solvent (also solid, liquid, or gas) and dissolves to form a solution which is a homogeneous mixture. A homogeneous mixture is uniform in composition and properties throughout. Pure substances, whether they are elements or compounds, are rarely found in nature.
