The interpretation already given in Part I of data on the sulphonation of naphthalene is now extended to the sulphonation of its monohydroxy‐ and its monoamino‐derivatives and of their common monosulphonic acids. The sulphamic acid intermediate theory of Bamberger 5 , recently modified and amplified by Alexander 2 , has been adopted and, together with the aid of the resonance theory discussed in Part I 1 , which indicates the activated or deactivated positions of the naphthalene nucleus, a logical explanation of the bewildering mass of data extant is provided.
