WebJan 23, 2024 · Boiling points of alkenes depends on more molecular mass (chain length). The more intermolecular mass is added, the higher the boiling point. Intermolecular forces of alkenes gets stronger with increase in the size of the molecules. In each case, the alkene … WebToxicity decreases with increase in the carbon chain length. Aromatic aldehydes are less toxic than low molecular weight aliphatic aldehydes. Low molecular weight aldehydes are highly flammable, with flammability decreasing with increasing carbon chain length. Low aromatic aldehydes are combustible or nonflammable liquids. Examples: Acetaldehyde

WebAside from the intermolecular interactions, however, the melting point depends also on how the molecules are packed or arranged in the solid form. The more symmetrical they are, the better they pack and form a perfect crystal lattice which results in a higher melting point.

Therefore, the “molecular weight” is really an average for the sample. To complicate the situation, there are several types of averages, depending on how the molecular weight is measured.

WebA High molecular weight increases the chemical resistance - to a point. It takes more damage to the main chains of the molecules before it will affect the strength of the material. A High molecular weight increases the viscosity of the material – makes it harder to process the material using conventional methods. http://www.passmyexams.co.uk/GCSE/chemistry/alkanes-physical-properties.html

WebDefinition: Homologs. Homologs are compounds that differ from each other by a repeating unit. We call this entire group of straight-chain alkanes the alkane homologous series. A homologous series is a family of compounds that have the same functional group, similar chemical properties, and the same general formula. WebThe meaning of FLAMMABILITY is ability to support combustion; especially : a high capacity for combustion.

WebThe alkanes from pentane through to C 16 are liquids with the remainder larger molecules being solids. All liquid alkanes are less dense than water and therefore float on it. The viscosity of liquid alkanes increases as the number of carbon atoms increase. From the physical properties of the alkanes, it can be established that: The steady ...
