The product of the following reaction has to be predicted – Concept Introduction: Apart from electrophilic substitution reactions, aromatic compounds undergo another type of reactions namely Aromatic nucleophilic substitution reactions. A nucleophile, unlike an electrophile is a species that is electron rich and always attracted towards electron deficient site. A nucleophile is mobile unlike electrophile. In aromatic compounds the site in the ring where there is deficient of electrons is attacked by the nucleophile. A new C-Nu bond is formed where ‘Nu’ is the nucleophile and ‘C’ is aromatic ring Carbon. In this process the bond between aromatic Carbon and the substituent bonded with it is broken. Let the substituent be ‘X’ that then C-X bond gets broken and C-Nu bond is formed. The substituent ‘X’ is termed as ‘Leaving group’. A good leaving is large in size with high electron affinity that they are capable to grabbing the bond pair electron and leaving form the aromatic C atom. Halogens are known to be excellent leaving group. The overall reaction can be represented as follows –

Concept Introduction:

Apart from electrophilic substitution reactions, aromatic compounds undergo another type of reactions namely Aromatic nucleophilic substitution reactions.

A nucleophile, unlike an electrophile is a species that is electron rich and always attracted towards electron deficient site. A nucleophile is mobile unlike electrophile.

In aromatic compounds the site in the ring where there is deficient of electrons is attacked by the nucleophile. A new C-Nu bond is formed where ‘Nu’ is the nucleophile and ‘C’ is aromatic ring Carbon. In this process the bond between aromatic Carbon and the substituent bonded with it is broken.

Let the substituent be ‘X’ that then C-X bond gets broken and C-Nu bond is formed. The substituent ‘X’ is termed as ‘Leaving group’. A good leaving is large in size with high electron affinity that they are capable to grabbing the bond pair electron and leaving form the aromatic C atom. Halogens are known to be excellent leaving group.

The overall reaction can be represented as follows –
