Flammability in hydrocarbons

WebThe flammability decreases with an increase in the carbon number. The reactivity of amines in general, is low. Examples: Aminocyclohexane Ethyleneimine Methylamine 2-Propylamine Aliphatic and Aclicyclic Hydrocarbons: Organic compounds composed solely of carbon and hydrogen. Hydrocarbons may be classified into 3 broad categories: WebThe flammable hydrocarbons are stable compounds with low reactivity. These compounds, however, may react violently with alkali metals and their alloys or with finely …

The noteworthy feature of saturated hydrocarbons is their inertness. Unsaturated hydrocarbons (alkanes, alkenes and aromatic compounds) react more readily, by means of substitution, addition, polymerization. At higher temperatures they undergo dehydrogenation, oxidation and combustion. Of the classes of hydrocarbons, aromatic compounds uniquely (or nearly so) undergo substituti… WebA flammable material is something that can burn (i.e., sustain a flame) in air under certain conditions.
