Introduction

Hey there! It looks like you're interested in the impact of introducing a hydroxyl group into a benzene ring on the reactivity of the aromatic ring towards substitution reactions. Let's dive into this topic!

Reactivity of Aromatic Ring with Hydroxyl Group

Introducing a hydroxyl group into a benzene ring can significantly impact the reactivity of the aromatic ring towards substitution reactions. The presence of the hydroxyl group can alter the electron density distribution in the benzene ring, affecting its reactivity.

The impact of introducing a hydroxyl group into a benzene ring on the reactivity of the aromatic ring towards substitution reactions can lead to: a) Enhanced Activity b) Diminished Activity c) Unchanged Activity d) Inability to Introduce a Hydroxyl Group into the Benzene Ring

Let's explore the impact of a hydroxyl group on the reactivity of the aromatic ring based on the available information.

Impact on Reactivity

The introduction of a hydroxyl group into a benzene ring generally enhances the reactivity of the aromatic ring towards substitution reactions. This is due to the electron-donating nature of the hydroxyl group, which increases the electron density in the benzene ring, making it more susceptible to electrophilic aromatic substitution reactions.

Conclusion

In summary, the introduction of a hydroxyl group into a benzene ring typically enhances the reactivity of the aromatic ring towards substitution reactions. This is primarily attributed to the electron-donating nature of the hydroxyl group, which increases the electron density in the benzene ring.
