If the tests for an aldehyde are negative, the unknown compound is a ketone. When once the compound has been established as an aldehyde or ketone, it is permissible to refer to tables of physical constants information thus obtained may be of value in indicating other possible groups to be tested for, with due regard to possible comphcations caused by the presence of these groups. 

Chapter XI is devoted to Qualitative Organic Analysis. The subject b discussed in moderate detail and this, coupled with the various Sections and Tables of Physical Constants of Organic Compounds and their Derivatives in Chapters III and IV, will provide a satisfactory course of study in this important branch of chemistry. No attempt has been made to deal with Quantitative Organic Analysb in this volume.

Many amines are regarded as being potentially carcinogenic those which are on the restricted list have been specified in the Tables of Physical Constants. 

Chapter 9, Investigation and Characterisation of Organic Compounds, contains much of the chemical information and preparative methods from the chapter previously entitled Qualitative Analysis. The emphasis of this chapter is now on achieving an understanding of chemical behaviour in association with spectroscopic features, and correlating this information to provide a definitive structural elucidation. In this way we hope that the material fulfils the requirements of a range of courses which deal in this topic. The tables of physical constants (Ch. 10) remain unchanged, and the appendices have been up-dated.. ...
