Do the molecules of alkanes have strong intermolecular forces and high melting points?
No, alkanes are non polar compounds and have low intermolecular attraction and low melting points.
Does the melting point depend on the substances being melted?
Yes, because the melting point depends on the strength of the intermolecular forces, which are different for different molecules and compounds. Stronger intermolecular forces mean a higher melting point.
What is an intermolecular force?
Intermolecular forces are any forces exerted on neighboring molecules of a given compound. The forces are not the actual chemical bonds present in the substance, but rather the substances own attractiveness to its own molecules. These intermolecular forces play a crucial role in determining a compounds various physical properties such as but not limited to :solubility, melting point, boiling point, density.
How is high melting and boiling points related to the structure of the compounds?
The structure of a compound will dictate what intermolecular forces hold the molecules together. The stronger these forces, the higher will be the boiling point.
What is the Weakest kind of intermolecular force?
The weakest of the four forces is gravity by a huge margin
What can you say about the relative strength of the intermolecular forces in the two compounds?
The intermolecular forces in acetone are weaker.
Why do covalent compounds and ionic compounds have different melting points?
Melting points are a reflection of the intermolecular forces and intramolecular forces of the compound. The stronger the intermolecular force, the more energy it takes to bring it to a different state.
How are the melting points of ionic compounds different from molecular compounds?
Very much higher.
Is the boiling point higher for compounds with a high viscosity?
Viscosity is the thickness of the compound. The thicker the compound the higher the intermolecular forces. The higher the intermolecular forces the higher the boiling point is.
How melting and boiling points are affected by intermolecular forces?
The stronger the intermolecular forces, the higher the melting point and boiling point. The weaker the intermolecular forces, the lower the melting and boiling points are.
How do you explain the solubility of compounds?
List all the intermolecular forces between solutes2) List all the forces between solvents3) List all the intermolecular forces between solvent and solute4) State the energy comparisons.
Do ionic or covalent hold two compounds together?
No, they do not hold two compounds together. The forces that hold compounds together are intermolecular forces. Ionic and covalent bonds are intramolecular forces, and they hold the atoms of the molecule or formula unit together.
Why do low temperatures and high pressures required to liquefy chlorine gas?
Chlorine molecules have weak intermolecular forces of attraction.
Do ionic compounds or covalent compounds have stronger intermolecular forces?
Intermolecular forces are the forces of attraction that exist between molecules in a compound. The stronger the attractions between particles the more difficult it will be to separate them. When substances boil, the particles are completely separated from one another and the attractions between the molecules are completely overcome.
Do the molecules of alkanes have strong intermolecular forces and high melting points?
No, alkanes are non polar compounds and have low intermolecular attraction and low melting points.
Is an apple a compound or mixture?
An apple is a mixture of many various compounds held together by Intermolecular forces
Organic compounds exist as discrete molecules with much weaker intermolecular forces than those seen in ionic compounds?
Organic compounds exist as discrete molecules with much weaker inter molecular forces than those seen in ionic compounds?
