2. Examine the diagram below. The elements E, T and S are hypothetical. A chemical reaction will take place. S Before After (a) If one of the two products of this reaction is TS,. The other product is an element. Draw the particles in the container after the reaction is complete. (b) Write a balanced chemical equation for this reaction: 2TE+4SE2+ 2TS2 (c) If each particle represents 0.20 moles.... (i) How many moles of TS, are made? (2x.20)+.20 =0.6 moles (ii) How many moles of the diatomic element are made? (ii) Which reactant is in excess? How many moles remain? (iv) How many molecules of TS, are in the container after the reaction is complete.
Classes Of Functional Groups
Organic Chemistry deals mostly with carbon and hydrogens, also called hydrocarbons, but those groups which replace hydrogen and bonds with carbon to give a characteristic nature, unique of their own, to the hydrocarbon they are attached to, are called functional groups. All the compounds belonging to a functional group undergo reactions in a similar pattern and are known to have similar physical and chemical properties.
Characteristics Of Functional Groups
In organic chemistry, we encounter a number of special substituent groups which are attached to the hydrocarbon backbone. These groups impart certain characteristics to the molecule of which it is a part of and thus, become the highlight of that particular molecule.
IUPAC Nomenclature
In Chemistry, IUPAC stands for International Union of Pure and Applied Chemistry which suggested a systematic naming approach for the organic and inorganic compounds, as in the beginning stage of nomenclature one single chemical compound was named in many ways by which lead to confusion. The need for this approach aroused as the number of chemical compounds newly discovered were increasing (approximately 32 million compounds) and the basic concept of nomenclature i.e. the trivial nomenclature and the derived system of nomenclature failed to overcome the challenge. It is an important task to name a chemical compound systematically and unambiguously which reduces lots of confusion about the newly reported compounds.
