Alkynes have greater boiling points than alkanes or alkenes, due to the fact that the electric field of an alkyne, with its increased number of weakly held π electrons, is more easily distorted, producing more powerful attractive forces in between molecules. WebAnswer (1 of 3): The basic assumption that this happens is flawed. Linear or less branched isomeric alkanes have higher boiling points as compared to branched alkanes assuming that both have comparable molecular masses. The boiling point of an entity depends upon the intermolecular forces of at...

WebDec 14, 2024 · Branching of an alkane chain makes the molecules more compact and brings various atoms closer. As a result, the molecular size decreases. This decreases the surface area and therefore the magnitude of Vander Waal’s forces also decreases. Hence the boiling point of the alkane decreases with branching. WebBy experimental observation, it is concluded that the alkenes do have higher boiling points due to the below-mentioned reason, Alkenes have more number of carbons compared …

WebThese boiling points are compared with those of the equivalent alkanes (methane to butane) with the same number of carbon atoms. Notice that: The boiling point of an alcohol is always significantly higher than that of the analogous alkane. The boiling points of the alcohols increase as the number of carbon atoms increases. WebIncreases. As the number of carbon atoms in a chain increases, the size of molecules increases. With increase in size, the intermolecular force of attraction also increases. …

WebIntermolecular forces of alkenes gets stronger with increase in the size of the molecules. In each case, the alkene has a boiling point which is a small number of degrees lower than the corresponding alkane. Do alkenes have higher boiling points? Boiling points of alkenes depends on more molecular mass (chain length).
