If the reaction sequence given below is carried out with 15 moles of acetylene, the amount of the product D formed (in g) is ____.
The yields of and are given in parentheses.
[Given : Atomic mass of ]
The yields of and are given in parentheses.
[Given : Atomic mass of ]
Answer: 136
Solution
From the reaction sequence with yields:
From the structure shown in the solution, appears to be a chlorinated aromatic compound. Based on the molecular formula, molar mass ≈ 75.5 g/mol.
Mass of = 1.8 × 75.5 ≈ 136 g.
- Starting with 15 mol acetylene
- After step 1 (50% yield): 15 × 0.5 = 7.5 mol of
- After step 2 (50% yield): 7.5 × 0.5 = 3.75 mol of
- After step 3 (80% yield): 3.75 × 0.8 = 3.0 mol of
- After step 4 (60% yield): 3.0 × 0.6 = 1.8 mol of
From the structure shown in the solution, appears to be a chlorinated aromatic compound. Based on the molecular formula, molar mass ≈ 75.5 g/mol.
Mass of = 1.8 × 75.5 ≈ 136 g.
