Edexcel IGCSE Chemistry syllabusChemistry 4CH1First assessment 2019

Practise writing combustion equations and distinguishing complete from incomplete combustion products of hydrocarbons.

How this is tested

  • complete and balance hydrocarbon combustion equations with CO2, H2O, CO or C as products
  • identify carbon monoxide, carbon or soot as products when oxygen supply is limited
  • add correct state symbols to combustion equations when the formulae and products are given

Question 5(b)(ii)

[Maximum number: 1]

Butane (C4H10)\left(\mathrm{C}_{4} \mathrm{H}_{10}\right) is an alkane.

Incomplete combustion can occur when the oxygen supply is limited.

One product of the incomplete combustion of butane is carbon monoxide.
Give the name of another product of this incomplete combustion.
