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.

Is propanoic anhydride or butanoic anhydride having a higher boiling point?
All else being equal/similar, the higer the molecular weight, the higher the boiling point.
Does chlorine have a higher boiling point than iodine?
iodine is having higher boiling point
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.
Is butane gas less volatile than propane?
Yes, the molecular mass of propane is 44 while that of butane is 58, higher is the molecular mass of an alkane higher would be the boiling point therefore less would be the volatility.
What doas paraffin mean?
1.a white or colorless, tasteless, odorless, water-insoluble, solid substance not easily acted upon by reagents, consisting of a mixture of hydrocarbons chiefly of the alkane series, obtained from crude petroleum: used in candles, for forming preservative coatings and seals, for waterproofing paper, etc. 2.Chemistry .a.any member of the alkane series. b.one of the higher members of the alkane series, solid at ordinary temperatures, having a boiling point above 300°C, which largely constitutes the commercial form of this substance. 3.Also called paraffin oil . British . kerosene.
How does the number of carbon atoms in a hydrocarbon atom affect its boiling point?
The more is the number of carbons in the alkane, the more is its boiling point.REASON:- As the number of carbon increases, the becomes the molecular mass. And the more is the molecular mass, the greater becomes the surface area which increases the van der Waal force of intermolecular attraction thereby increasing the boiling point of the alkane.NOTE:- Among isomers (of the same alkane), the structure which have more # of side chain has less BP because more the # of side chains are present, more will the structure will be closer to the shape of a sphere, therefore will have smaller surface area.-by spd831
What is the boiling point of liquid paraffin?
Paraffin is a class of hydrocarbons called Alkane the most basic alkane being methane. Methane has a boiling point of -161 degree Celsius. As it goes higher the bp increases as the energy required to break the hydrogen bonding increases.
Does chlorine or oxygen has higher boiling point?
Chlorine has higher boiling point.
Why does isomerisation turn straight chain alkanes into alkanes with lower boiling temperature?
Isomerisation causes straight chain alkanes to become branched alkanes which prevents the chains from moving to close proximities of each other. This reduces the van der Waal's intermolecular forces between chains so less energy is needed to overcome the forces and thus a lower boiling point.
Which has the higher temperature - boiling water or ice?
boiling water
How does pressure affect boiling point?
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
How does salt effect boiling point?
The boiling point is higher.
