What is the relationship between the boiling point of the alcohol and the number of atoms in its molecules?

Alcohols are polar compounds. Now if the number of molecules is less the attraction is more and then the boiling point is high. Hence the relation.

What is the connection between the size of the molecules in crude oil and their condensing or boiling point's?
Smaller molecules have a lower boiling point, and larger molecules have a higher boiling point. Source: Learnt this in class today.
What is altered when a liquid at its boiling point is converted to a gas at the same temp 1 Size of the molecules 2 Distance between molecules or 3 Kinetic energy of molecules?
distance between molecules
Why ethyl alcohol is vapor?
It's not technically speaking, a vapour. But it is a volatile liquid (It readily evaporates). Boiling point is to do with the interactions between the molecules in a liquid. The stronger the interaction, the more energy is required to pull them apart. So the energy (heat) supplied at it's boiling boiling point is sufficient to break the interactions in ethanol. The boiling point of ethanol is 78.1 °C.
Why does alcohol boils first than wster?
Due to the Hydrogen bonds existing beween water molecules.The electronegative oxygen causes a dipole in water molecules.The slightly positive hydrogens of one water molecule bond to the slightly negative oxygens of other water molecules. This bond formed between many water molecules results in water having a higher boiling point than alcohol. Alcohol only has Van der vaal's forces existing between their molecules and these forces are weaker than hydrogen bonds.
What is the difference between the process of boiling and evaporation of water?
Boiling is a greatly expedited form of evaporation. When you heat something to its boiling point, it has enough energy for its molecules to rapidly escape. Evaporation is a much slower action, generally. It is just molecules at the surface gaining enough energy to escape. Both evaporation and boiling are endothermic processes. They will cool what ever the molecules are escaping from.

What has a higher boiling point alcohol or water?
Water has a higher boiling point that alcohol (ethanol). The main reason for this is because water has stronger intermolecular forces holding the molecules together.
Why is the boiling point of phenol greater than alcohol?
This is because the intermolecular forces holding the molecules of phenol together are stronger than the intermolecular forces holding the molecules of alcohol together.
How does polarising power effect boiling point?
Polar molecules have relatively weak intermolecular forces. Intermolecular forces and boiling point have a direct relationship, so due to the fact that polar molecules have weak forces, their boiling points will be lower.
What is the relationship between intermolecular forces and vaporization points?
The greater the potential of a liquid's molecules to interact with each other through intermolecular forces, the lower the vapour pressure is going to be above the liquid (because molecules will preferentially stay liquid and interact with other molecules rather than fly away as a gas), and the lower the boiling point of the liquid. Therefore the relationship is an inverse one.

distance between molecules
How do attractions between molecules could cause polar water to have a higher boiling point than non polar carbon dioxide?
Because their relationship was so strong they can do anything <3

II. The distance between the molecules.
Which evaporates faster alcohol or ether?
There are two reasons for this; {1} boiling point: Tthe boiling point of water is greater than that of ether. So when the boiling point is greater then the vapour pressure will be low. {2} intermolecular forces: The second is intermolecular forces. When intermolecular forces are greater then the the boiling point will be greater and if boiling point is greater then the vapor pressure will be low. The inter molecular forces of water is greater than that of ether and so the vapour pressure will be low and and boiling point will be greater.
