tertiary reactions are the most common type of elementary reactions

) and is, therefore, a first order reaction. Rate = k [RX] The order of reactivity depends upon the stability of carbonium ion formed in the first step. Since the 3 carbonium ion is most stable, the ionization of tertiary alkyl halide is favored. The order of reactivity for S N ..

Reversible Reactions, Irreversible Reactions and Equilibrium - It is a common observation that most of the reactions when carried out in closed vessels do not go to completion, under a given set of conditions of temperature and pressure. Infact in all such ca..

Series Reactions (First Order) - A complex reaction involving two series reactions can be of the type, A reacts to give B, which is then transformed to C. Both the elementary reactions (1) and (2) exhibit first - order kinetics, that is, F..

Electrophilic Substitution Reactions - All amino groups -NH 2 , -NHR, -NR 2 are most powerful activating groups in aromatic electrophilic substitution reactions are ortho and para directing. Aniline gets instantaneously brominated at all of the three O, p - positions to give a w..

Rate of Chemical Reactions - Everyday experience tells us that chemical reactions take place in widely varying rates. Infact rates of various reactions vary from very slow to very fast. Some reactions are so rapid that they occur as soon as the reactants are ..

Distinction between Primary, Secondary and Tertiary Amines - 1 o , 2 o and 3 o can be distinguished by carbyl amine test. Primary amines form carbylamine with an offensive odor. Secondary amines give no reaction with chloroform and alcoholic KOH. Tertiary amines do not..

Introduction - We observe various chemical processes in our daily life. It is a common observation that the rates of these chemical reactions vary and depend on certain factors. The knowledge of the rate of a reaction is of importance in industries to ensure optimum pr..

Molecularity - Elementary reactions are classified according to their molecularity. The number of reacting species, which are involved in simultaneous collision to bring about a chemical reaction is called the molecularity of the reaction. In a unimolecular h..

Allergy is defined as the body's hypersensitive reaction to a foreign substance that it comes in contact with or that enters the body. The foreign substance that causes allergy is called the allergen. There are various types of allergens causing a variety of allergies. Pollen g..

Protons and neutrons Nuclear forces Electromagnetic repulsion between the protons Nuclear fusion and fission reactions Radioactive isotopes Three most common forms of radioactive decay (alpha, beta, gamma) Changes in the nucleus in each type of decay Alpha..
