1.	Which are the various steps of electrophilic substitution of benzene ?
Answer» Solution :Electrophilic (E) Substitution (S), reactions of benzene are shortly KNOWN as aromatic `S_(E)`. Aromatic `S_(E)` REACTION occurs in three steps : (i) Steps involve in formation of electrophile (ii) Steps involve in formation of intermediate which is a slow STEP. (iii) Step involve in liberation of PROTON from intermediate carbocation (`sigma`-complex) and produce substituted product This step is fast and is not rate determining.
