The polarity of the molecules determines the forces of attraction between the molecules in the liquid state. Polar molecules are attracted by the opposite charge effect (the positive end of one molecule is attracted to the negative end of another molecule. Molecules have different degrees of polarity as determined by the functional group present.
Principle: The greater the forces of attraction the higher the boiling point or the greater the polarity the higher the boiling point.
alcohol=because of inter molecular force eg : hydrogen bonding,van der waals dispersion forces and dipole-dipole interaction that have the capabilities. This attraction are stronger as the molecule get longer and have more electron and also the presence of only one oxygen vs. the two in the acid functional group.

Does chlorine have a higher boiling point than iodine?
Yes, chlorine has a higher boiling point than iodine. Chlorine has a boiling point of -34.6 degrees Celsius, while iodine has a boiling point of 184 degrees Celsius.
Will LiCl have a higher boiling point than water?
No, LiCl (Lithium chloride) will not have a higher boiling point than water. The boiling point of water is 100 degrees Celsius, whereas the boiling point of LiCl is significantly higher at 1382 degrees Celsius.
Ethanol c2h5oh and methyl ether ch3och3 have the same molar mass.W hich has a higher boiling point?
Ethanol (C2H5OH) has a higher boiling point compared to methyl ether (CH3OCH3) due to hydrogen bonding in ethanol. Hydrogen bonding results in stronger intermolecular forces in ethanol, requiring more energy to overcome, hence a higher boiling point.
Is Boiling is the maximum temperature a substance can reach?
Boiling is the temperature at which a substance changes from a liquid to a gas. It is not necessarily the maximum temperature a substance can reach, as some substances can be heated to higher temperatures without boiling.
Which has higher boiling point Urea or Sodium chloride?
Sodium chloride (NaCl) has a higher boiling point than urea. This is because sodium chloride forms ionic bonds which are stronger than the hydrogen bonds in urea. Stronger bonds require more energy to break, resulting in a higher boiling point.
Why alcohol have higher boiling point than alkanes?
Alcohols have higher boiling points than alkanes because alcohols can engage in hydrogen bonding between the hydroxyl (-OH) groups, which increases the intermolecular forces between molecules. This stronger intermolecular attraction requires more energy to break the bonds and thus results in a higher boiling point for alcohols compared to alkanes, which only have weaker London dispersion forces.
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 is the order according to increasing boiling point of ketones alcohols alkanes and carboxylic acid?
Firstly, remember that a large member of any series is likely to have a higher boiling point than a small member of another series. Given that we assume we are dealing with similar sized molecules, alkanes will have the lowest bp's, as the molecules are non polar so we have only van der Waals forces. Ketones will come next as the carbonyl group is polar so there will also be dipole-dipole interactions. Alcohols and carboxylic acids come next, in that order, as they also have hydrogen bonds.
Do alcohol and orange juice have different physical propities?
Most of the common alcohols are colorless liquids at room temperature. Methyl alcohol, ethyl alcohol, and isopropyl alcohol are free-flowing liquids with fruity odours. The boiling points of alcohols are much higher than those of alkanes with similar molecular weights.
Which has higher boiling point aldehyde or ketone?
the alkanes are saturated and contains more atoms so therefore contain more electrons this results in stronger dispersion forces the alkenes and unsaturated contain less atoms less electrons weaker dispersion force compared to the alkane
Does Ether have a higher boiling point than alcochol?
no..ethers are always low in boiling point than alcohol due to alcohols hydrogen bonds
Why do boiling points change between primary alcohols and seconrady alcohols?
as branching increases, the molecules are held relatively far away, and so they experience only weak intermolecular (or van der Waals) force of attraction. so as branching increases, boiling point decreases.
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.
Why do aldehydes and ketones have lower boiling points than their correspending alcohols?
Ketones and aldehydes do not have hydrocarbon atoms which bond to nitrogen or oxygen, individual molecules do not hydrogen bond to each other which makes them have lower boiling points than alcohols.
Why is acid anhydride having higher boiling point than alkane?
Molecules with dipoles have higher boiling points because they are able to form strong dipole-dipole interactions with other molecules. Alkanes are nonpolar and only have weak London dispersion forces, thus lower boiling points.
Does 2-butanol have a higher boiling point than butanoic acid?
Butanoic acid has a higher boiling than butan-2-ol, indeed almost all carboxylic acids have higher boiling points than their equivalent alcohols as they are able to form dimers with each other through Hydrogen Bonding.
Why do haloalkanes have a higher boiling point than alkanes?
cycloalkanes have a higher boiling point than alkanes because there are more points of contact between the carbon-carbon chain, and thus more intermolecular Van Der Waal (or London) forces. Similarly, the boiling point of alkanes increases as the length of the carbon chain increases. This is because more intermolecular forces are present, hence more energy in heat form is required to break the bonds. Branching in the alkanes reduces the boiling point as it reduces the points of contact.
