Question

Alkane general gives clean flame why

Answer 1

Alkanes have less amount of carbon content in them..with sufficient oxygen all will burncleanly. Alkanes general formula is CnH(2n+2). The higher the amount of carbon in a hydrocarbon,the more oxygen and more heat is required to convert all of the carbon to CO2. ... That's why alkanes generally burn with a clean flame.
