a.

Compounds S and T belong to the homologous series called the alkanes. What is the general formula of the alkanes?

[1]
b.

Which homologous series does compound R belong to?

  • Alcohols
  • Alkenes
  • Carboxylic acids
  • Esters

c.

Compound P, C2H4\text{C}_2\text{H}_4C2​H4​, burns in a limited supply of oxygen to undergo incomplete combustion, producing carbon monoxide, CO\text{CO}CO, and water, H2O\text{H}_2\text{O}H2​O. Write the balanced symbol equation for this reaction.

[1]
d.

In a car's catalytic converter, carbon monoxide and nitrogen monoxide react according to the equation:

2CO+2NO→N2+2CO2 2\text{CO} + 2\text{NO} \rightarrow \text{N}_2 + 2\text{CO}_2 2CO+2NO→N2​+2CO2​

During a journey, 242 g of carbon dioxide is produced. Calculate the volume of carbon monoxide, in dm3\text{dm}^3dm3, removed from the exhaust gases. (Take the molar gas volume at RTP as 24 dm3/mol. Relative atomic masses: C=12.0\text{C} = 12.0C=12.0, O=16.0\text{O} = 16.0O=16.0)
