Yes, shorter alkane molecules are generally more flammable compared to longer alkane molecules. This is because shorter alkane molecules have a higher vapor pressure, which allows them to vaporize more easily and ignite at lower temperatures.

Are longer chain alkanes more flammable than shorter chain alkanes?

Shorter chain alkanes are generally more flammable than longer chain alkanes. This is because shorter chain alkanes are more volatile and readily vaporize, making them easier to ignite. Longer chain alkanes are less volatile and require higher temperatures to vaporize and ignite.


Which compound may be formed when alkanes are cracked?

When an alkane is cracked, alkenes and shorter alkanes are produced.


Pharmaceutical uses of alkane?

The pharmaceutical use of alkane is often used in general anesthesia. Alkane is a compound of halothane which is a general anesthetic agent.


Could someone explain the differences in changes of state in terms of intermolecular forces of attraction between a short molecule i.e. methane and a longer molecule i.e. pentane.?

In the absence of any other functional groups, the longer the alkane (pentane is longer than methane), the greater will be the intermolcular forces. Thus, it will take more energy to change states for the longer molecule than the shorter (b.p. will be higher, etc.). This arises from the fact that the more carbon atoms (or the more atoms, in general), the greater will be the dispersion forces. These may very well be the only intermolecular forces present, if there are no dipoles, or hydrogen bonding.


What is an alkane in which a halogen atom replaces one or more hydrogen atoms on a carbon chain?

halo alkane or alkyl halides


What molecule is CH3 CH2 CH2 CH2?

One you're not too likely to run into--methanidylpropane. More common are C4H10 (propane) or C4H8 (several things, usually butadiene resin)


What is an alkane with one or more attached alkyl groups?

An alkane with one or more attached alkyl groups is called a branched alkane. Branched alkanes have alkyl groups (such as methyl, ethyl, etc.) branching off the main carbon chain, which can affect their physical and chemical properties compared to straight-chain alkanes.

Why alkene gives more soot than alkane?

Comparing ethane and ethene . there proportionally more hydrogens in ethane. Conversely there are proportionally more carbons in ethene. Ethane C:H:: 1:3 or 1/3 : 1 Ethene C:H :: 1:2 or 1/2 : 1 Since the fraction '1/2' > 1/3' then more carbon (soot).
