Question
When a hydrocarbon A undergoes complete combustion it requires 11 equivalents of oxygen and produces 4 equivalents of water. What is the molecular formula of A ? (A) C11H8 (B) C11H4 (C) C5H8 (D) C9H8
Answer: D
💡 Solution & Explanation
CxHy + 4 y x O2 CO2 + y H2O a y x a y a given 4 y x a = 11a y x = 11 y a = 4a y = 8, Then x + 8/4 = 11 x = 9 Formula = C9H8 | JEE(Main) 2023 | DATE : 31-01-2023 (SHIFT-2) | PAPER-1 | OFFICIAL PAPER | CHEMISTRY PAGE # 2
