Question

(b)

Alkanes in petrol burn in air.
The equations represent two reactions of hexane burning in air.
Reaction 1 2C6H14 + 1902-12CO2 + 14H₂O
Reaction 2 2C6H14+ 1302 12CO + 14H₂O
Reaction 2 produces a different carbon compound to Reaction 1.
Name the carbon compound produced in Reaction 2.
(i)

Answer 1

In Reaction 2, the carbon compound produced is carbon monoxide (CO). This compound is produced when hexane (C6H14) burns in air, along with water (H₂O). Carbon monoxide is a toxic gas that is produced when hydrocarbons burn incompletely, and it can be harmful to humans and animals if inhaled.
