Vedclass · Answer

(B) $1$. In sulphonation of benzene,the effective electrophile is sulphur trioxide $(SO_3)$.$2$. In Friedel-Crafts acetylation,the effective electrophile is the acylium ion $(CH_3-C \equiv O^{+})$.$3$. In formylation (Gattermann-Koch reaction),the effective electrophile is the formyl cation $(HC \equiv O^{+})$,which is generated in situ from $CO$ and $HCl$ in the presence of a Lewis acid like $AlCl_3$.

In the sulphonation,acetylation and formylation of benzene,the group of effective electrophiles would be:
