Benzene also undergoes electrophilic substitution when refluxed with fuming sulphuric acid for several hours. This is called sulphonation. The electrophile is the SO3 molecule and the product formed is benzenesulphonic acid, C6H5SO3H. Suggest which atom in the SO3 molecule accepts an electron pair in the mechanism of sulphonation.
