Question 13.8:-

Write chemical equations for combustion reaction of the following hydrocarbons:

(i) Butane

(ii) Pentene

(iii) Hexyne

(iv) Toluene


Combustion can be defined as a reaction of a compound with oxygen. 

(i) 2C4H10(g) + 13O2(g)     8CO2(g) + 10H2O + Heat    Butane(ii) 2C5H10(g) + 15O2(g)   10CO2(g) + 10H2O(g) + Heat      Pentane(iii) 2C6H10(g) + 17O2(g)   12CO2(g) + 10H2O(g) + Heat     Hexyne

(iv) +9O2(g)7CO2(g)+4H2O(g)+Heat

Toluene
