this is because of the presence of intermolecular hydrogen bonding in the polar molecules. energy is needed to over come the attractive forces resulting in higher boiling point values.

Which one have higher boiling point alcohol or phenol?
Phenol has a higher boiling point than alcohol does; it has a stronger dipole difference in its -OH group.
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.
What would be the boiling point of alcohol at a higher altitude?
it depends on the altitude
Why boiling point of ethyl alcohol is higher as compared to dimethyl ether?
The presence of strong hydrogen bonding in ethyl alcohol (when compared to that of dimethylether) increases its boiling point.
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

What is the structural isomer of C8H18 with the lowest boiling point?
In organic chemistry, alkanes such as C8H18 have structural isomers. The more these isomers are branched the lower the boiling point is. The reason for this, is that un-branched alkanes have a higher mass area, they are more likely to have more potential points of attachments for other atoms or molecules which would then raise intramolecular forces thus increasing boiling points. The structural isomer of C8H18 that has the boiling point is systematically known as 2,2,3,3-tetramethylbutane.
Do long hydrocarbons have a higher boiling point then short hydrocarbons?
This is true as far as we are talking about alkanes. As the size of an alkane chain increases the boiling point increases because the relatively low van der Waals forces increase with mass. The higher the vdw forces the more energy required to break apart two molecules and thus higher boiling points.
How can one differentiate between water and alcohol with tasting or smelling it?
Boil/Freeze it. The alcohol will have a higher boiling point and lower freezing point than the water will.
Why can't and alcohol thermometer be used to measure the boiling point of water?
Because the boiling point of alcohol is lower than the boiling point of water.
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.
Liquid alcohol will change to vapor when its temperature reaches the A boiling point B fusing point C freezing point D melting point?
A given form of liquid alcohol will turn to vapor at its boiling point, which is different for each type of alcohol.
