Question

Where would the site for Electropholic Aromatic Substitution occur for the molecule shown below?

Answer 1

Here the electrophillic aromatic substitution reaction occurs it means that the attack of electrophile takes place.The attack of electrophile will be done at that position in which electron density is more.

The electron density depends on the type of substituent attached i.e whether it is a activating or deactivating group.

Lectron releasing group this acts as activating group and hence increases negative charge density increases at ortho position (not ar pana as it is - Electron with drawing group this acts as a deactivating group and increases negative charge, density meta position to it that is at positions a Thus the position position Electrophilic ortho to the neto. to the substitution occurs at electron releasing group electron with drawing the and group substitution occurs at position This a electrophilic shown,
