Página 230 - In the second place, the hydrogens (1) and (3), (2) and (4), (3) and (5), (4) and (6), (5) and (1), and (6) and (2) bear to each other the same relation, but a different relation from that which the above pairs do. Replacing any such pair, we would have a second compound, which is represented by the general formula X HCX yCX xcr H Formula II.
Página iii - For this reason, special care has been taken to select for treatment such compounds as best serve to make clear the fundamental principles. General relations as illustrated by special cases are discussed rather more fully than is customary in books of the same size ; and, on the other hand, the number of compounds taken up is smaller than usual. The author has endeavored to avoid dogmatism, and to lead the student, through a careful study of the facts, to see for himself the reasons for adopting...

Página 346 - It leads him to observe, to experiment, to think, to originate. Coming as it does from the working laboratory of a practical instructor, who has had the constant advice of fellow-teachers in all parts of the country, this text may be fairly taken as an exponent of the latest methods of teaching chemistry. Its distinctive features are : experimental and inductive methods ; the union of descriptive and qualitative chemistry, thus allowing these kindred branches to supplement and illustrate each other...
Página 347 - The book is based upon plans and methods which have been employed in the author's laboratory throughout a series of years, and no work has been incorporated in the text or in the exercises that has not there been proven practicable. A wide correspondence with the best teachers in all parts of the country shows that they are pursuing essentially the same plan. Throughout the book the aim is to make the labors of the teacher as light as possible, and to "place the laboratory work where it will do the...
Página 231 - ... facts of less importance known which furnish arguments in favor of the benzene hypothesis expressed in the formula above discussed, but this is not the place to consider them. Let it suffice, for the present, to recognize that the hypothesis is in accordance with the most important facts known to us. There is one point which has not been touched upon, and that is the relation of the carbon atoms to each other. In regard to this, as well as to the relation between the carbon atoms in ethylene...
Página iii - Special care has been taken in selecting for treatment such compounds as will best serve to make clear the fundamental principles. General relations as illustrated by special cases are discussed rather more fully than is customary in books of the same size ; and, on the other hand, the number of compounds taken up is smaller than usual, though all which are of real importance to the beginner are treated of with some degree of fulness.
Página 345 - The whole book is a practical sermon on this text. In no other elementary book in the English language will the student find so many admirably chosen examples of the formation of structural formulae. The important facts are noted ; then the inference is drawn ; then the hypothesis is ventured upon ; analogous facts are recalled ; the hypothesis is strengthened or weakened : suggestions are made ; experiments are conducted ; and all is finally summarised in the formula. But the book i more than a...

Thus there is less danger of confusion than when a larger number is brought to the attention of the student. The author has endeavored to avoid dogmatism, and to lead the student, through a careful study of the facts, to see for himself the reasons for adopting the prevalent views in regard to the structure...
