Why 2-methyl-1-butene have higher boiling point than 1-pentene?

The C2 carbon of 2-methyl-1-butene is an sp2 configuration: It is connected to a methyl group and to the rest of the skeleton chain. There is a dipole generated from both of the sp3 carbons towards the C2 carbon, mainly due to the difference in sigma bond strengths. Sigma bonds are stronger than pi bonds, making it slightly more electron pulling. So, having a higher "s" character in sp2 (33% s) will pull dipoles of sp3 (25% s).
There is no dipole generated between a hydrogen and an sp2 carbon. The net dipole strength is therefore stronger in 2-methyl-1-butene than 1-pentene. Since boiling points depend on dipole and London forces, 2-methyl-1-butene will bind better to each other than 1-pentene, thus will have a higher boiling point.

Does chlorine or oxygen has higher boiling point?
Chlorine has higher boiling point.
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.
What C7H16 isomer has the highest boiling point?
Heptane - longer the chain, higher the boiling point. Least amount of branches, higher the boiling point.
A student measures the boiling point of rainwater and sea water.Which has the higher boiling point?
Sea water has higher boiling point,as it contains sodium chloride
How does IMF affect the boiling point or melting point of a substance?
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.

How does salt effect boiling point?
The boiling point is higher.
Which substance has higher boiling point nitrogen fluoride or NH3?
Boiling point of NH3: -33,34 0C Boiling point of NF3: -129,1 0C The boiling point of ammonia is higher.
What happens if boiling point is higher than melting point?
The boiling point is always higher than the melting point.
Does chlorine have a higher boiling point than iodine?

How does IMF affect the boiling point or melting point of a substance?
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.
How does normal boiling points differ from other boiling points of the same liquid?
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.
Which substance would have a higher boiling point sodium chloride or water?
Sodium chloride has a higher boiling point.
