I have two questions, this is a take home review in my university course
List the most important (strongest) intermolecular forces that must be overcome to
a) remove water of hydration from NiSO4 7H2O
b) vaporize liquid CH3 OH
The second question is..
Consider what happens when solid CsI dissolves in liquid CH3OH
a) What type of attractive forces must be overcome in the liquid CH3OH?
b) What type of forces must be onvercome in the solid CsI?
c) What type of attractive forces are important when CsI dissolves in liquid CH3OH?
Any help is greatly appriciated!
To remove water of hydration from NiSO4 7H2O ion-ion dipole is the strongest intermolecular forces needs to overcome since the partial negative charge of oxygen atoms of the polar water molecule will cause them to attract to the positively charges Ni2+ ion so inorder to remove water molecule from this we must disrupt the intercation between the positive Ni2+ ion and the negative dipole on the oxygen atom.
in case of CH3OH the hydrogen bonding between the oxygen and hydrogen of will be the strongest intermolecular force that will need to overcome.
