The electron-donation of -OH reinforces the electron-withdrawing by -NO2 . Also, resonance increases distance between the charges. Charge separation is maximum for p-nitrophenol, therefore, it has maximum dipole moment. <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-tvr8maqtghsj.png" />

Q. Which of the following compounds will have the highest dipole moment?

The electron-donation of $- O H$ reinforces the electron-withdrawing by $- N O_{2}$ . Also, resonance increases distance between the charges. Charge separation is maximum for p-nitrophenol, therefore, it has maximum dipole moment.
