Question

What attractive forces must be overcome when CsI is dissolvedin
liquid HF?

Answer 1

The attractive forces must be overcome are :

• Ion- ion interaction

• Dipole - Dipole

• Hydrogen Bonding

Step-by-step explanation:

For the compound to dissolve the attractive forces existing between atoms of the compound must be reduced

CsI is ionic compound and its molecules are held together by ionic(electrostatic) force . These force must be weakened for its dissolution

Forces in HF :

1 .Hydrogen Bonding : In HF strong intermolecular Hydrogen Bonding exist between the electronegative F and Hydrogen

2. Dipole - dipole : HF is polar . So it is a permanent dipole and has dipole diople interaction
