it is polar. therefore, dipole-dipole and dispersion forces (always present)

These are London dispersion forces.

H2CO has a greater intermolecular force than CH3CH3. This is because H2CO can form hydrogen bonds due to the presence of a highly electronegative oxygen atom, while CH3CH3 can only participate in weaker dispersion forces.
The relative strength of intermolecular forces depends on the types of molecules involved. Compounds with hydrogen bonding, such as water, tend to have stronger intermolecular forces compared to those with only London dispersion forces, like diethyl ether. This results in higher boiling points for compounds with stronger intermolecular forces.
The intermolecular forces in Cl2 are London dispersion forces, which are the weakest type of intermolecular force. This occurs due to temporary fluctuations in electron distribution.
The strength of intermolecular forces is directly related to the boiling point of a substance. Substances with stronger intermolecular forces require more energy to break those forces, leading to a higher boiling point. Conversely, substances with weaker intermolecular forces have lower boiling points.
The stronger the intermolecular forces, the higher the melting point and boiling point. The weaker the intermolecular forces, the lower the melting and boiling points are.

CH3NH2 has the higher boiling point as it has a hydrogen bond between the molecule which is a stronger intermolecular attractive force, whereas CH3CH3 only has covalent bonds which are weaker intermolecular attractive forces.
The intermolecular forces of CH3F include dipole-dipole interactions and London dispersion forces. The molecule has a permanent dipole moment due to the difference in electronegativity between carbon, hydrogen, and fluorine atoms, leading to dipole-dipole attractions. Additionally, London dispersion forces, which result from temporary fluctuations in electron distribution, also contribute to the intermolecular forces in CH3F.
The dominant intermolecular force in CH2Br2 is London dispersion forces. These forces arise from temporary fluctuations in electron density that create temporary dipoles. There may also be some contribution from dipole-dipole interactions due to the presence of polar C-Br bonds.
Intermolecular forces, specifically hydrogen bonding between methyl alcohol molecules, must be overcome for methyl alcohol to evaporate. The hydrogen bonds between molecules need to be disrupted in order for the liquid to transition into a gas during evaporation.
Intramolecular forces are not intermolecular forces !
The relative strength of intermolecular forces depends on the types of molecules involved. Compounds with hydrogen bonding, such as water, tend to have stronger intermolecular forces compared to those with only London dispersion forces, like diethyl ether. This results in higher boiling points for compounds with stronger intermolecular forces.
hydrogen bonding
Both molecules, CH3CH2CH2NH2 and H2NCH2CH2CH2NH2, exhibit hydrogen bonding due to the presence of nitrogen and hydrogen atoms that can form hydrogen bonds with each other. Additionally, they may also experience dipole-dipole interactions and London dispersion forces.
The intermolecular forces are hydrogen bonding.
When there is more thermal energy, then there are less intermolecular forces.
The strength of intermolecular forces is directly related to the boiling point of a substance. Substances with stronger intermolecular forces require more energy to break those forces, leading to a higher boiling point. Conversely, substances with weaker intermolecular forces have lower boiling points.
