In the combustion reaction of alkanes if Ethane is used how many moles

1.	In the combustion reaction of alkanes if Ethane is used how many moles of oxygen are required?(a) 3(b) 4(c) 7(d) 3.5The question was asked by my college professor while I was bunking the class.My enquiry is from Hydrocarbons topic in section Hydrocarbons of Chemistry – Class 11
Answer» The correct choice is (d) 3.5 To EXPLAIN I WOULD say: The combustion reaction of alkanes has a standard reaction that is CnH2n+2 + (3n/2 + 1/2)O2 → nCO2 + (N + 1)H2O. In the case of combustion of ethane, n = 2. That means the number of moles of oxygen REQUIRED is 3(2)/2 + 1/2 = 3.5
