Recently I was introduced to organic chemistry for the first time.
In the section of complete and incomplete combustion of carbon compounds, they provide example of two different objects, namely a cooking gas burner and a candle, and said that "complete combution can be seen in burner but incomplete combustion can be seen in candle"
The explanation was
Apart from unsaturated carbon compound present in candle while saturated carbon compound present in burner's gas help in complete combution as less energy is required to break single bond in gas than double and triple bond in candle wax"
But also that
the holes in burner help in mixing of oxygen more to perform complete combution but candle's thread dont allow much easy mixing of oxygen thus insufficient oxygen supply cause incomplete combution"
Can anyone explain the second reason in more detail?
I can't understand how holes help in mixing oxygen thus providing sufficient oxygen supply for the gas to combust? Why can't a candle thread provide sufficient oxygen?
One more thing , where does the reaction between oxygen and gas take place in the burner? Inside it or outside the burner once the gas comes out of the holes?
