Answer to Question #276764 in Chemistry for michelle

Question

In the complete combustion reaction of cyclohexane, how many C=O bonds are formed

Answer 1

Solution:

Cyclohexane is a cycloalkane with the molecular formula C₆H₁₂.

The complete combustion reaction of cyclohexane:

C₆H₁₂(l) + 9O₂(g) → 6CO₂(g) + 6H₂O(l)

According to stoichiometry, 6 molecules of CO₂ are formed

Each molecule of CO₂ is made up of 2 C=O bonds

Thus, (6 × 2) = 12 C=O bonds

Answer: 12 C=O bonds are formed
