Answer 2

Complete oxidation of one mole of an  alkane forms 3 moles of CO2. The alkane  is Propane.

• When an organic compound is completely oxidized, heat energy along with water and carbon dioxide is released.
• The carbon in carbon dioxide comes solely from the organic compound being burnt.
• Since 1 molecule of CO₂ has 1 C atom, so when 3 moles of CO₂ are produced, the organic compound should have 3 C atoms.
• Since it is mentioned that the organic compound being burnt is an alkane, hence the only three-carbon alkane possible is propane with the formula CH₃CH₂CH₃.
• The complete reaction is:

        CH₃CH₂CH₃ +  5 O₂ → 3CO₂ + 4 H₂O
