Okay I need an explanation from YOU. when is this due? If it’s last minute, why didn’t you do it when you had time? This is very irresponsible, unless you have a personal reason. Please quit commenting on others just for the points. I helped you with one, because I thought it was just one question you needed help with. No one is going to finish this for you. I’m sorry but it’s the truth, everyone here needs help. No one is here TO help. So please be cooperative and try to learn. Of course, I’m sorry if it is for a very personal reason as it happens to everyone where you need the work ASAP because of a reason. Hopefully, it’s not because you were lazy. Appreciate your education as not many people in the world have it.

bagirrra123 [75]

Answer:

The attractive forces must be overcome are :

  • Ion- ion interaction
  • Dipole - Dipole  
  • Hydrogen Bonding  

Explanation:

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

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

Forces in HF <em>:</em>

<em>1 .Hydrogen Bonding :  In HF strong intermolecular Hydrogen Bonding exist between the electronegative F and Hydrogen</em>

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