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
alkanes have higher melting points than alkenes. Van der Waals forces are present between molecules of alkanes and alkenes, and the strength of the can der Waals forces is porportional to the melting/boiling point of the alkanes/alkenes
Since the strength of the van der Waals forces is dependent on the number of electrons, and alkanes have more electrons (with additional 2 hydrogen atoms) compared to an alkene with same number of carbon atoms, thus alkanes generally have higher melting points
Even though they are about the same, ketones have a higher boiling point.
With the same number of carbon atoms, the alkane has a higher BP.
alkene because its not saturated
Alkenes have a higher melting points.
Alcohols!
ketones
octane
Chlorine has higher 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.
Heptane - longer the chain, higher the boiling point. Least amount of branches, higher the boiling point.
Sea water has higher boiling point,as it contains sodium chloride
The stronger the IMF, the higher the boiling point and the lower the melting point. The weaker the IMF, the lower the boiling point and the higher the melting point.

The boiling point is higher.
Boiling point of NH3: -33,34 0C Boiling point of NF3: -129,1 0C The boiling point of ammonia is higher.
The boiling point is always higher than the melting point.
iodine is having higher boiling point
Heptane - longer the chain, higher the boiling point. Least amount of branches, higher the boiling point.
Higher then the boiling point of the solvent.
Sea water has higher boiling point,as it contains sodium chloride
The stronger the IMF, the higher the boiling point and the lower the melting point. The weaker the IMF, the lower the boiling point and the higher the melting point.
The normal boiling point is the boiling point at sea level, or more precisely, at 1 atmosphere pressure. At higher elevations, or at lower atmospheric pressures, the boiling point is lower. At higher atmospheric pressures, the boiling point is higher.
The magnesium chloride solution has a higher boiling point.
