Does butane undergo substitution or combustion
Butane can undergo both substitution and combustion reactions, depending on the conditions and reactants involved.
Substitution: In the presence of a halogen such as chlorine or bromine, butane can undergo a substitution reaction where one or more hydrogen atoms are replaced by halogen atoms. For example, in the reaction with chlorine gas, butane can undergo chlorination to form chlorobutane.
Combustion: When butane reacts with oxygen in the presence of a spark or flame, it undergoes combustion to produce carbon dioxide and water as the main products. This is a highly exothermic reaction and is the basis for the burning of butane in lighters and gas stoves.
