Chemistry - GOC Question with Solution | TestHub

Solution:

The activity of o- and p-directors depends on their electron-donating ability.

Order: Anionic $(-{\mathrm{O}}^{-})$ > lone pair donor $(-\mathrm{OH})$ > resonance-hindered donor $(-{\mathrm{OCOCH}}_3)$ > hyperconjugation $(-{\mathrm{CH}}_2{\mathrm{CH}}_3)$.
