Which of the following reactions is an example for incomplete combustion?

Correct answer

3

Step-by-step solution

Complete combustion of a hydrocarbon involves the reaction of the fuel with sufficient oxygen to produce carbon dioxide and water as the only products. Incomplete combustion occurs when there is insufficient oxygen, leading to the formation of products like carbon monoxide or elemental carbon (soot) instead of carbon dioxide. Analyzing the given reactions: 1. The first reaction is C ₄ H ₁₀ + 13 2 O ₂ 4 CO ₂ + 5 H ₂ O . This is complete combustion of butane. 2. The second reaction is the oxidation of isobutane to te
