Q.Identify the main product of the reaction.
CH3-CH2-CH3 --O2, heat-->

Step 1. Identify the reaction. Heating an alkane (propane) with O2 is combustion, section 15.1.5.

Step 2. Write the balanced equation. CH3-CH2-CH3 + 5 O2 --heat--> 3 CO2 + 4 H2O, following the chapter's general pattern CnH2n+2 + (3n+1)/2 O2 -> n CO2 + (n+1) H2O + heat (n=3: (3x3+1)/2 = 5). …

Applying the general alkane combustion equation CnH2n+2 + (3n+1)/2 O2 -> n …

• Answering carbon monoxide, which is specifically the INCOMPLETE combustion product (limited O2) -- excess O2, as implied by plain combustion conditions, gives complete combustion …
