Major type of attractive force for KCI?
dipole-dipole attraction
• ionic bond
• dispersion forces
• hydrogen bond
The major type of attractive force for KCI (potassium chloride) is the ionic bond. KCI consists of ions, specifically potassium (K+) and chloride (Cl-) ions, which are held together by the electrostatic attraction between opposite charges.
The major type of attractive force for KCI (potassium chloride) is the ionic bond.
The major type of attractive force for KCI (potassium chloride) is the ionic bond. To understand this, we need to know that KCI is an ionic compound composed of positively charged potassium ions (K+) and negatively charged chloride ions (Cl-).
Ionic bonds occur between two atoms when one atom donates one or more electrons to the other atom, resulting in the formation of positively and negatively charged ions. In the case of KCI, the potassium atom donates one electron to the chlorine atom. This transfer of electrons creates electrostatic attractions between the positively charged potassium ions and the negatively charged chloride ions, forming an ionic bond.
Dipole-dipole attractions occur between polar molecules having a permanent dipole moment due to the unequal sharing of electrons. However, KCI does not have polar covalent bonds, so dipole-dipole attractions are not the major type of attractive force for this compound.
Dispersion forces, also known as London forces, are the weakest type of intermolecular force. They occur between non-polar molecules or atoms and arise from temporary fluctuations in electron distributions that create momentary dipoles. Although dispersion forces may be present between KCI molecules, they are relatively weaker compared to the ionic bond.
Lastly, a hydrogen bond occurs when a hydrogen atom is bonded to an electronegative atom (like oxygen, nitrogen, or fluorine) and another electronegative atom in a different molecule or chemical group. Since there are no hydrogen atoms bonded to electronegative atoms in KCI, hydrogen bonding is not a major factor in its attractive forces.
Therefore, the correct option is that the major type of attractive force for KCI is the ionic bond.
