JEE Main levelSingle correct optionDifficulty 2 of 3mc040
Complete combustion of ethane follows 2CX2HX6+7OX24COX2+6HX2O. The volume of COX2 at STP formed from 6.0g of ethane is (C = 12, H = 1; 22.4Lmol−1):
A13.44L
B4.48L
C17.92L
D8.96L
Answer: D
n(CX2HX6)=6.0/30=0.20 mol. Each mole gives 2 mol COX2, so 0.40 mol. V=0.40×22.4=8.96L.
