II. The Foundations of Organic Chemistry A. The branch of chemistry specializing in the study of carbon compounds. 1. Organic molecules are molecules containing carbon. 2. Called organic molecules because these compounds were only found in living beings. 3. Vitalism a. Belief in a life force outside the jurisdiction of chemical/physical laws. b. Organic chemistry in early 19th century was built...

A series of oxygen-rich organic peroxide compounds each containing two bis(hydroperoxy)methylene groups is described. Energetic testing shows that these compounds are much less sensitive toward impact and friction than existing classes of organic peroxides. The compounds are highly energetic, which may lead to practical peroxide-based explosives.

indole is a nitrogen-containing heterocycle. it is a very important motif in agriculture and pharmacy. many compounds containing indole moiety has been isolated form nature. it is also an important part in natural alkaloids. tryptophan is an amino acid which posses indole. 3-sustituted indoles are the main group of its derivatives. because the wide-spread application of 3-substituted indolic co...

We have established two classification rules that statistically accurate allow to separate carcinogenically active chemical compounds from inactive chemical compounds. The electronic and information properties of molecules are used as molecular descriptors. The threshold values of descriptors that characterize and determine the presence or absence of carcinogenic properties of chemical compound...

Sulfur (S) serves many purposes in the ruminant animal. It is a component of amino acids methionine and cystine, as well as B-vitamins, biotin and thiamine and a number of other organic compounds. Elemental S, sulfates, sulfuric acid, and hydrogen sulfide all may be present in ruminant nutrition. Elemental S, sulfates, and sulfuric acid are relatively non-toxic. Hydrogen sulfide, however, is hi...

Soil pollution by the presence of different contaminants (e.g. heavy metal ions or pesticides) is one of the biggest problems worldwide. The positive affinity of natural humic acids towards these contaminants might contribute to the soil and ground water protection; therefore it is necessary to study the reactivity and barrier properties of humic acids. An original reactivity-mapping tool based...

The standard procedure for the determination of chlorine in organic compounds of mercury consists in decomposition of the material, separation of mercury and determination of chlorine as chloride. Decomposition of the sample could be achieved by wet mineralization [1,2], ignition in a stream of oxygen [3—7] or nitrogen [8], ignition in a flask with oxygen [9], etc. [10, 11]. Chlorine and mercur...
