How does flammability depend on chain length
WebAs you go up the fractionating column, the hydrocarbons have: lower boiling points lower viscosity (they flow more easily) higher flammability (they ignite more easily) This means … WebHowever, whenever a synthetic polymer is made, chains of varying length (varying n’s) are produced, and the product has a range of formula weights. 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.

WebThe flammability parameters of gases and liquids include flammability limits, burning velocity, and heat of combustion. 1 The flammability limits are the most commonly … 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 ...

WebOct 4, 2008 · The flammability DECREASES as the chain length increases. Methane (C1) is natural gas and by definition very flammable. C20 is basically paraffin wax and it will burn … 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.
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.
