(17)can anyone solve question 17
Homework Answers
Option 3 is false.
Explanation:-
1. Hydrogen bonds are long and weak, covalent bonds are short and strong.
2. Liquid water is more dense than solid because after freezing water orientation of H-bond causes molecules to push apart, which lower the density of water.
3. Only Hydrogen bonds are broken when water vaporises, not covalent.
4. Energy absorbed when Ice turned to iquid.

7. If an ionic bond is stronger than a dipole-dipole interaction, how can water dissolve an ionic compound? None of these The ion-dipole interactions of a bunch of water molecules gang up on the strong ionic bond and pull it into the solution. The ions never overcome their interatomic attraction and therefore are not soluble. The ionic bond is weakened by the ion-dipole interactions and ionic repulsion ejects the ions from the crystal. The ion-dipole...
