Expert Answer
The gaseous aliphatic organic compound = CnH3nOm
Volume= 1 mL
The balanced reaction for the combustion is,
CxHyOz + (x+y/4-z/2)O2 → xCO2 + y/2H2O
Here, x=n, y=3n, z=m
Hence, the balanced reaction for the combustion of given organic compound will be,
CnH3nOm + (n+3n/4-m/2)O2 → nCO2 + 3n/2 H2O
At RT, the volume of H2O is ognored as it becomes liquid,
Hence, contraction in volume = 1 + n + 3n/4 - m/2 - n = 1+ 3n/4 - m/2
Therefore, the correct answer option is D.
