Answer #1

CH3 CH2 CH2 CH2 CH3 ---------------------> dispersion forces

explanation: this is completely non-polar molecule no matter of dipole -dipole and hydrogen bond

H2CO ------------------------> dipole-dipole

explanation: the O is attached to the carbon, it's bound to create a dipole by pulling the shared electrons in the covalent bond more closer to itself, making the carbon delta positive and the oxygen delta negative.

CH3CH2OH --------------------> hydrogen bonding

explanation:

hydrogen bond formed between hydrogen of one alcohol and another alochol oxygen

O2 --------------------> dispersion forces

Select which of the following statements regarding miscibility is correct. a) Experiment shows that CH3(CH2)4CHO is basically immiscible in water! This experimental result may not have been predicted as they are both polar species. b) If chemical species are miscible in one another, the interactions between the two species must be weaker than those in the pure samples. c) NaCl is insoluble in hexane; this means that the ionic forces in NaCl must be stronger than the ion-induced dipole forces...

When would a molecule with only London dispersion forces/induced dipole-induced dipole have a higher boiling point or melting point than a molecule with stronger intermolecular forces? Some examples of these cases would be nice. My best guess is when the molecule w/ London dispersion forces is a solid compared to something else w/ H-bonding or dipole-dipole that's a gas. But I am not positive about that.
