The standard molar enthalpy of vaporisation \(\left(\Delta_{\text {vap }} H^{\circ}\right)\) of \(A, B\) and \(C\) liquids is \(23.3,41\) and \(29 \mathrm{~kJ} \mathrm{~mol}^{-1}\) respectively. The correct order of diople-dipole attractive forces in these liquids is
- A \(B>C>A\)
- B \(B>A>C\)
- C \(A>C>B\)
- D \(A>B>C\)
Answer & Solution
Correct Answer
(A) \(B>C>A\)
Step-by-step Solution
Detailed explanation
( The enthalpy of vaporisation is the amount of heat that must be added to a liquid substance to transform it into a gas. Dipole-Dipole interactions are intermolecular force of attraction between polar molecules. Stronger the dipole-dipole interactions, higher will be the heat…
