An organic compound is estimated through Dumas method and was found to evolve 6 moles of CO ₂, 4 moles of H ₂ O and 1 mole of nitrogen gas. The formula of the compound is:
Options
- AC ₁₂ H ₈ ~N
- BC ₁₂ H ₈ ~N ₂
- CC ₆ H ₈ ~N ₂
- DC ₆ H ₈ ~N
Correct answer
C. C ₆ H ₈ ~N ₂
Step-by-step solution
[ C _ x H _ y ~N _ z ] Dumas method 6 CO ₂+4 H ₂ O + N ₂ Mol of CO ₂=6, so mol of C is =6 Mol of H ₂ O =4 , so mol of H is =8 Mol of N ₂=1, so mol of N is =2 Formula is C ₆ H ₈ ~N ₂
