Answer: and
are hydrogen boding,
and
are ion-dipole forces.
Explanation: If the bond is formed between a metal and a non metal then it is known as ionic bond and ionic compounds have positive and negative ions and so they have ion-dipole forces. Aluminium chloride and Iron(III)bromide both are ionic as they have a bond between a metal and non metal and so both of these have ion-dipole forces.
Ammonia and ethanol both are polar molecules and we know that polar molecules have dipole-dipole forces.
A hydrogen bond could form if hydrogen is bonded with more electron negative atom(N, O or F).
In ammonia, H is bonded to N and in ethanol, H is bonded to O, so both of these molecules must have hydrogen bonding. Since hydrogen bond is stronger as compared to dipole - dipole forces, we will say that both ammonia and ethanol have hydrogen bonding.
Answer: and
have ion-dipole interactions.
and
have hydrogen bonding.
Explanation:
and
have ion-dipole interactions.
and
have dipole-dipole forces. ‘H’ atom is bonded to ‘N’ in ammonia and ‘H’ atom is bonded to ‘O’ in ethanol, therefore; both ammonia and ethanol must have hydrogen bonding. Hydrogen bond is stronger with compared to dipole-dipole forces, hence; hydrogen bond gets the priority than dipole-dipole forces.
Further explanation:
Inter molecular forces are the physical forces between molecules.
London dispersion forces are occurring between two non-polar molecules and these are the weakest inter molecular forces of the inter molecular forces.
Dipole-dipole forces are occurs between two polar molecules. Many molecules are polar and hence this is a common inter molecular force.
Ion-dipole forces occur when an ion encounters a polar molecule. A cation will attract to the negative part of the molecule and an anion will attract to the positive part of the molecule.
Hydrogen bonds are the attraction of molecules which are already in other chemical bonds and these types of bonds are primary electrostatic force.
Ammonia is a polar molecule. Ethanol
is a very polar molecule.
and
are ionic compounds and dissociate to give ions.
Hence and
have ion-dipole interactions.
and
have dipole-dipole forces. ‘H’ atom is bonded to ‘N’ in ammonia and ‘H’ atom is bonded to ‘O’ in ethanol, therefore; both ammonia and ethanol must have hydrogen bonding. Hydrogen bond is stronger with compared to dipole-dipole forces, hence; hydrogen bond gets the priority than dipole-dipole forces.

In resonance structures, the chemical connectivity in the molecule is same but the distribution of electrons are different around the structure. They are created by moving electrons in double or triple bonds, and not atoms.
Phenol, and methanol,
both are alcohols that contain an
group attached to carbon atom.
Due to loss of 1 from phenol, it forms phenoxide anion and due to presence of double bond in the benzene ring the negative charge on the oxygen atom (which represents electrons) will resonate with double bonds of benzene ring as shown in the image. The resonance-stabilized phenoxide ion is more stable. Whereas when methanol lose 1
it forms methoxide anion and there are no such electrons present in the structure of methoxide that will result in the movement of electron. Since, due to resonance-stabilized phenoxide ion is more stable than methoxide ion, so it is a stronger acid.
The structures of the anions resulting from loss of 1 from phenol and methanol is shown in the image.
