derivatives of second order

The general formula of Haloalkane (CnH 2 n + 1 - X) or Haloarene is 'RX' where R - is an alkyl or aryl group and X is a halogen atom (F, Cl, Br or I). The halogen derived hydrocarbons are a highly reactive class of compounds. The reactivity is due to the presence of polar carbon..

Haloarenes are colorless liquids or crystalline solids. Aryl halides are heavier than water. Being heavier than water, they are insoluble in water but soluble in organic solvents. The melting and boiling points of aryl halides are nearly the same as those of alkyl halides containing the ..

Every organism has a tendency to increase its entropy, which is very much in accordance with the second law of thermodynamics. In order to maintain its organisation at the molecular, cellular and organismic levels, every organism is forced to obtain energy from its surroundings..

Reading - Strategies - What is reading? Is it something that one does only in the classroom to pass examinations? While reading, we are interacting with a written text. This interaction with a text helps not only in decoding information, but also in enjoying the text for its own sake. In order..

>All aldehydes and ketone with type group give haloform reaction. Carboxylic acids are prepared by oxidation of primary alcohols, aldehydes and alkenes, by hydrolysis of nitriles and by treatment of Grignard reagents with carbon dioxide. Aromatic carboxylic acids can also be prepared by side chain ..

Initial Rate Method - This method is used for reactions where more than one reactant species are involved. Initial rates of the reaction are determined by varying the concentration of only one reactant while keeping the concentrations of other reactants constant. Initial rate of reaction correspond..

Nomenclature of Aliphatic Amines - Aliphatic amines are named by adding the suffix amine to the name of the alkyl group and it is written as one word. E.g., C 2 H 5 NH 2 is Ethylamine. When two or more alkyl groups in secondary or tertiary amines are some, the prefix di or tri i..

Scientific Methodology - Science is basically a collection of knowledge and information that is obtained by observation and testing of natural world, in a logical and orderly manner, and its interpretation. Hence, the basis of science is its orderly, step-wise procedure called s..

From this statement it follows that total energy of the universe, For e.g., system and surroundings taken together as always constant during any physical or chemical process. In order to derive mathematical expression for first law of thermodynamics let us assume that a system ..

A first-order differential equation is said to be linear if, in it, the unknown function y and its derivative y' appear with non-negative integral index not greater than one and not as product yy' either. Hence, a first-order linear differential equation is of the for..
