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.
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.
What is the relationship between molecules?
The relationship between molecules is primarily defined by the interactions and bonds that hold them together and influence their behavior. Molecules can form through covalent bonds, where atoms share electrons, or ionic bonds, where electrons are transferred between atoms. Additionally, intermolecular forces, such as hydrogen bonding and van der Waals forces, dictate how molecules interact with one another, affecting properties like boiling point and solubility. Overall, the molecular relationship is foundational to understanding chemical reactions, biological processes, and material properties.
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.
Does alcohol or water evaporate faster?
Alcohol typically evaporates faster than water under the same conditions due to its lower boiling point. Alcohol molecules have weaker intermolecular forces, allowing them to escape into the air more readily.
What is the relationship between boiling point and pressure?
The relationship between boiling point and pressure is that as pressure increases, the boiling point of a substance also increases. This is because higher pressure makes it harder for molecules to escape into the gas phase, requiring more energy to reach the boiling point. Conversely, lower pressure decreases the boiling point as it allows molecules to escape more easily.
Why is the boiling point of phenol greater than alcohol?
Phenol has stronger intermolecular forces (hydrogen bonding) between its molecules compared to alcohol. This stronger bonding requires more energy to break apart, resulting in a higher boiling point for phenol compared to alcohol.
What is the relationship between boiling point and vapor pressure?
The relationship between boiling point and vapor pressure is that as vapor pressure increases, the boiling point decreases. This is because higher vapor pressure means that the liquid molecules are more likely to escape into the gas phase, leading to a lower boiling point.
Do alcohols have higher boiling points compared to other substances?
Yes, alcohols generally have higher boiling points compared to other substances due to the presence of hydrogen bonding between alcohol molecules.
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.
Which one have higher boiling point alcohol or phenol?
Phenol has a higher boiling point than alcohols. This is because phenol molecules can form intermolecular hydrogen bonds due to the presence of the hydroxyl group attached to the aromatic ring, leading to stronger attractive forces between molecules compared to alcohols.
What is the Boiling point of alcohol mixing with water?
The boiling point of a mixture of alcohol and water depends on the ratio of the two substances. For example, a solution of 20% alcohol and 80% water will have a boiling point higher than either pure alcohol or water. The boiling point elevation is due to the interactions between the alcohol and water molecules.

Why boiling point of ethyl alcohol is higher as compared to dimethyl ether?
The boiling point of ethyl alcohol is higher than that of dimethyl ether because ethyl alcohol has stronger intermolecular forces (hydrogen bonding) between its molecules than dimethyl ether, which only has weaker van der Waals forces. These stronger intermolecular forces in ethyl alcohol require more energy to overcome, resulting in a higher boiling point.

The boiling point of ethanol is 78.1 °C.
Is boiling alcohol and then considering the vapor a chemical change?
Yes, boiling alcohol and considering the vapor is a physical change as it does not alter the chemical structure of the alcohol molecules. The alcohol vapor can be condensed back into liquid alcohol without undergoing a chemical change.
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.
