Which has higher boiling point aldehyde or ketone?

Answer 1

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

Answer 2

In general, aldehydes have lower boiling points than ketones due to the presence of a hydrogen bond in aldehydes that is absent in ketones. This hydrogen bond in aldehydes results in weaker intermolecular forces compared to ketones, leading to lower boiling points.

Answer 3

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

Answer 4

Even though they are about the same, ketones have a higher boiling point.

Answer 5

With the same number of carbon atoms, the alkane has a higher BP.

Answer 6

alkene because its not saturated

Answer 7

Alkenes have a higher melting points.

Answer 8

Alcohols!

Answer 9

ketones

Answer 10

octane
