JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
One mole of an alkane (x) requires \(8\) mole oxygen for complete combustion. Sum of number of carbon and hydrogen atoms in the alkane (x) is _______.
- A 15
- B 17
- C 19
- D 21
Answer & Solution
Correct Answer
(B) 17
Step-by-step Solution
Detailed explanation
The general formula of an alkane is \(C_n H_{2n+2}\). The balanced chemical equation for the complete combustion of an alkane is: \(C_n H_{2n+2} + \left(\dfrac{3n+1}{2}\right) O_2 \rightarrow n CO_2 + (n+1) H_2O\) Given that \(1\) mole of the alkane requires \(8\) moles of…
