\( 5\,L\) of an alkane requires \(25\,L\) of oxygen for its complete combustion . If all volumes are measured at constant temperature and pressure, the alkane is
- A Isobutane
- B Ethane
- C Butane
- D Propane
Answer & Solution
Correct Answer
(D) Propane
Step-by-step Solution
Detailed explanation
Since the compound undergoing combustion is an alkane. Hence the combustion reaction can be written as \(\underset{5L}{\mathop{{{C}_{n}}{{H}_{2n+2}}}}\,+\underset{25L}{\mathop{\left( \frac{3n+1}{2} \right){{O}_{2}}}}\,\to \) \(nC{{O}_{2}}+(n+1){{H}_{2}}O\) since volumes are…
