Identify the major type of attractive force between the particles of each of the following:
Which one is
KCI
dipole dipole attraction
ionic bond
dispersion forces
hydrogen bond
KCI is an ionic compound, so the major type of attractive force between its particles is an ionic bond.
For KCI (potassium chloride), the major type of attractive force between the particles is ionic bond.
Ionic bond: This occurs between positively and negatively charged ions. In KCI, the potassium ion (K+) with a positive charge attracts the chloride ion (Cl-) with a negative charge.
In terms of the other options you mentioned:
Dipole-dipole attraction: This type of attractive force occurs between polar molecules. KCI is not an example of dipole-dipole attraction because it contains ions.
Dispersion forces: Also known as London dispersion forces or Van der Waals forces, these are present in all molecules and are caused by temporary shifts in electron distribution. However, for KCI, the attractive force is primarily an ionic bond.
Hydrogen bond: This type of attractive force occurs between a hydrogen atom bonded to an electronegative atom (such as oxygen, nitrogen, or fluorine) and another electronegative atom. KCI does not involve hydrogen bonding.
To identify the major type of attractive force between the particles of KCI, we need to consider the nature of the particles involved.
KCI consists of potassium (K+) ions and chloride (Cl-) ions.
1. Ionic Bond: The bonding between K+ and Cl- ions in KCI is primarily an ionic bond. Ionic bonds occur between two oppositely charged ions, in this case, the positively charged K+ ion and the negatively charged Cl- ion. Ionic bonds are often formed between metals and nonmetals.
Hence, the major attractive force between the particles in KCI is an ionic bond.
Note: Dipole-dipole attractions, dispersion forces, and hydrogen bonds are different types of intermolecular forces that occur between molecules, rather than between ions. They do not apply to ionic compounds like KCI, where ions are present.
