QUESTION: 1

The electrophile involved in the sulphonation of benzene is

Solution:
Nitration and sulfonation of benzene are two examples of electrophilic aromatic substitution. The nitronium ion (NO2+) and sulfur trioxide (SO3) are the electrophiles and individually react with benzene to give nitrobenzene and benzenesulfonic acid 
Concentrated sulphuric acid contains traces of SO3 due to slight dissociation of the acid.
Dissociation:  This is a reversible splitting up of a compound. In this case, the sulphuric acid splits into water and SO3, and at the same time these combine back together again to make sulphuric acid. The overall effect is that concentrated sulphuric acid contains small amounts of SO3.
Fuming sulphuric acid, H2S2O7, can be thought of as a solution of SO3 in sulphuric acid - and so is a much richer source of the SO3.
