A) Heat of vaporization
B) Vapour pressure at the same temperature
C) Boiling points
D) Gaseous densities at the same temperature and pressure
Correct Answer: D
Solution :
In\[C{{H}_{3}}C{{H}_{2}}OH,\]there is intermolecular H-bonding while it is absent in isomeric ether \[C{{H}_{3}}OC{{H}_{3}}\] Larger heat is required to vaporise\[C{{H}_{3}}C{{H}_{2}}OH\] as compared to\[C{{H}_{3}}OC{{H}_{3}},\]thus is incorrect. \[C{{H}_{3}}C{{H}_{2}}OH\] is less volatile than\[C{{H}_{3}}OC{{H}_{3}},\]thus vapour pressures are different, thus is incorrect. bp of\[C{{H}_{3}}C{{H}_{2}}OH>C{{H}_{3}}OC{{H}_{3}},\]thus is incorrect. \[Density=\frac{mass}{volume},\]due to ideal behaviour at a given temperature and pressure volume and molar mass are same. Hence, they have same vapour density.You need to login to perform this action.
