Science > Chemistry > Introduction to Organic Chemistry > Chemistry of Carbon Compounds Organic chemistry is a branch of chemistry, which studies carbon compounds. Organic substances are substances derived from organisms like plants and animals. In the olden days it was assumed that these substances cannot be prepared in laboratories. Berzelius assumed that some vital […]

Modern Periodic Table
In the last article, we have studied the initial classification of elements. In this article, we shall study the modern periodic table. Moseley’s Criteria: Henry Moseley, a physicist from England in the year 1913, observed that when certain metals were bombarded with high-speed electrons, X-rays are emitted. He studied the frequencies of the X-rays emitted and found that […]
In this article, we shall study the initial classification of elements and Mendeleev’s periodic table. Need for Classification of Elements: With the rapid advance and developments in science, the number of discovered elements increased. Due to a large number of elements, it is difficult to study and remember the behaviour and properties of each and every element. Hence attempts have […]

Hydrogen Fluoride
The gaseous compound formed when dry fluorine gas reacts with dry Hydrogen, gas is called hydrogen fluoride. Hydrogen fluoride gas on condensation forms liquid hydrogen fluoride which is also referred to as anhydrous hydrogen fluoride or anhydrous hydrofluoric acid. When vapours of hydrogen fluoride are dissolved in water, the resulting aqueous solution is known as […]

Fluorine
In this article, we shall study halogen member fluorine. Fluorine is positioned in Group 17 and the second period of the periodic table. It is highly reactive. Occurrence: Because of extreme reactivity fluorine does not occur in the free state. It occurs as the fluorides (F–) of certain metals such as Calcium and Aluminium. Its […]
Science > Chemistry > Biomolecules > Disaccharides and Polysaccharides In the last article, we have studied monosaccharides. In this article, we shall study disaccharides and polysaccharides. Disaccharides: Di-saccharides on hydrolysis give two molecules of monosaccharide. They on hydrolysis with dilute acids or enzymes yield two molecules of either the same or different monosaccharides. e.g. Cane sugar (Sucrose) […]

Glucose and Fructose
Science > Chemistry > Biomolecules > Glucose and Fructose In the last article, we have seen what are carbohydrates and how are they classified. Based on hydrolysis behaviour the carbohydrates are classified into three types. a) Mono-Saccharides b) Oligo-Saccharides and c) Poly-Saccharides. In this article, we shall study monosaccharides in detail particularly glucose and fructose. […]

Carbohydrates
Science > Chemistry > Biomolecules > Introduction to Carbohydrates All those simple or complex organic and inorganic substances found in different living forms are collectively called as biomolecules. Biomolecules can be grouped into two types micro and macromolecules. The micro molecules have moderate to low molecular mass. e.g. sugars, amino acids, and their derivatives, vitamins, […]
Ascertaining property rights of an unborn is essential as it has a direct implication on the rights of other existent individuals. Although the Indian laws recognize the existence of an unborn as a legal person, rights are not granted until the birth of the child. Further, while a child in a mother’s womb is considered […]
Indian Legal System > Civil Laws > The Code of Civil Procedure > Terminology of CPC In this article w shall study the terminology of the code of civil procedure. These are the terms and phrases used in civil proceedings, decree, and judgment. Abatement of a Suit: Thus the termination of a suit by operation […]
